High speed flight, rockets, space travel, time travel etc
« on: December 28, 2018, 11:16:50 AM »
In another thread people got to talking about high speed rockets, missiles etc.

When I was a youngster, I was very interested in this but later in life found out
that it was mostly a mathematical exercise with lots of really difficult math
involved.

'Ri-ight'

767MPH x 27  = 20,000 MPH within the earth's atmosphere ?

Close to sea level ?

 :ROFL:

so the Kremlin has alien technology ?

A rocket has to travel 25,000 mph within the earths atmosphere to escape it. USSR been shooting rockets into space since the 1950's. Getting rockets to travel hypersonic speeds through thicker atmosphere has been the challenge. America already done it. Russia and China aren't far behind. It would be hard to defend if shot at a city or aircraft carrier. It's easier to shoot down a bullet with another bullet than shoot down a hypersonic missile with another hypersonic missile. The price to defend against that kind of weapon would skyrocket with low success rates.

Why don't you look up to see how fast those Apollo flights went. None of them achieved 25000 mph
on the trip to the moon, but were able to get going nearly that fast coming back.

Apollo 10 set the record for the highest speed attained by a manned vehicle: 39,897 km/h (11.08
km/s or 24,791 mph) on May 26, 1969, during the return from the Moon.

Certainly not 25000 mph within the atmosphere....

Escape velocity is not achieved getting into orbit which requires only enough speed to continuously fall off the earth.  From there speed is built up in stages to slingshot out of Earth's gravity.

Hmm.

What BillyB has got wrong is escape velocity - the speed to break free of orbit or at least enter stable orbit.  The 25,000 miles/hr figure given out is the speed needed to break through the upper stratosphere/mesosphere/thermosphere/exosphere and enter orbit when travelling horizontal to earth.

In order to escape the gravitational field of the earth, when travelling vertically, a rocket can go at just about any speed, as long as the acceleration does not fall below 9.8 m/s^2.  It is possible to escape earth's gravitational field at 1 mph going vertically, but that would take an enormous amount of fuel.  Therefore rockets bound for space initially lifts off vertically and then turns over to accelerate at a slight angle at the upper atmosphere, where air density is low and air resistance is weak. 

FYI, SR-71 Blackbird was certified to fly at Mach 3.2, a little less than 2,000 miles/hr, at 85,000 feet.   The speed limitation was dictated by the maximum air temperature at the engine compressor inlet, which was about 400 degree C.  Exceeding Mach 3.2 would raise the external temperature of the aircraft (from air friction) to dangerous levels.

They achieved 23,400+ mph to get out of the earth's atmosphere using the gravitational pull of the moon to help counter earth's gravity. Physics website after physics website says 25K mph is the approximate speed that's needed to escape earth....without the help of the moon. Nobody is talking Apollo rockets anyway. We're talking the capabilities of rockets in general. Fastest American rocket has achieved over 35K mph and you think 25K hasn't happened yet. I can believe Russia having a new hypersonic weapon as recently announce in the news. Even if 10% of the hypersonic rockets are successful, it can still do a lot of damage carrying nukes. Firing off 10 hypersonic rockets at a carrier with one being successful is also a good trade off if it brings down the ship and 70+ aircraft.

So,

Are we all ( finally ) agreed that 25,000 MPH at ( near sea level ) isn't possible, yet ?

Or are those using google (and not paying  attention)  going to pretend they're 'correct' ;)

It's not at all possible to travel anywhere near that speed shooting something
at sea level to something else at sea level, however, it might be entirely possible
to fire something up out into space then turn it back towards the Earth and get
traveling very, very, very fast using the Earths gravity to assist.

ICBM's can travel up to over 1200 miles (1900 km) above sea level enroute to a
target and hit the Earth at 15,000 mph (24140.16 kph). That is significantly less
than 25,000 mph but it's really fast.

The Earth travels around the Sun at 67,000 mph (107,000 km/h) so in theory
you could send a satellite or weapon arching towards the sun use a gravity
assist and then have that weapon meet the Earth forward in it's orbit and
it would be traveling very very fast in relationship to the Earth when it hit. 

Could Russia design something that would do that? Probably, would they?
No chance. A weapon that takes weeks or months to strike Earth would
be pretty useless when ICBM's can arrive in 30-40 minutes.

A missile doing 25,000 mph at sea level is possible under specific circumstances and probably has been possible for a number of years. It's simply not been practical or useful.

The PM article FT posted said the Avangard missile was lifted high up into the atmosphere but not space by an ICBM or newer version then the missile was released from inside the ICBM at a preset altitude.

The carry vehicle, the ICBM, would protect the missile from the dangers of friction for a time and help the Avangard missile gain speed. When released from the ICBM, possibly on the earthward trajectory, the Avangard missile's engines plus the pull of gravity from the Earth would push the missile to even greater speeds. Hitting 15,000 mph or even 20,000+ mph on a simple downward trajectory to impact the Earth should be simple enough to achieve if the ICBM released the Avangard missile at close to the Karman line, 62 miles above the Earth where the atmosphere ends and space is said to begin

The part of the article I find impossible to believe is if Putin is saying the Avangard missile was able to transition from vertical or near vertical flight to horizontal flight at very low levels and hug Earth's terrain and evade hills, mountains and even trees and then hit a specific target such as a building or a moving target such as an aircraft carrier at 15,000+ mph.

Traveling at 15,000+ mph there'd be no need for an explosive in the Avangard missile. Simple kinetic energy on impact would destroy a building of any size or an aircraft carrier. To destroy a city would require a nuclear device and could be set off by reaching a specific location determined by GPS or timer or something else.

Firing off 10 hypersonic rockets at a carrier with one being successful is also a good trade off if it brings down the ship and 70+ aircraft.

A carrier is at sea level.  A hypersonic rocket travelling horizontally at just above terrain height would explode due to heat build up from air friction long before it ever gets near it's target.  One carrying a nuke would be a danger to the nation firing it.

The speeds being mentioned is at above stratosphere height, closer to space or in space. 


Lasers would be a better choice for near instant targeting, or kinetic accelerator weapons that fire solid inert rounds.   The speed of a kinetic projectile will fall off drastically over any long distance, but would still travel too fast for the capability of any dynamic defensive countermeasures.

For a pure theoretical exercise, a 1 kg inert projectile travelling at 25,000 mph would impart about 62.4 MJ of energy, or about 15,000 calories.  For simplification of what type of damage such a projectile would do, we can associate the energy of creating a crater as being equal to evaporating a similar amount of water.  At 25 deg C, it takes 2,450 kJ to evaporate 1 kg of water.  So, a little over 25 kg of water would be evaporated, or 25 liters.  It would create a 1 meter wide crater that would be about 30 cm deep.

For practical purposes, such a projectile, of even a missile's mass, would more than likely puncture through any object it hits.  Something soft enough to crush on impact rather than pierce would disintegrate long before it reaches its target.

ICBMs are sub-orbital velocity
the USSR proposed a system in the 1970s called "FOB" Fractional Orbital Bomb
put a nuclear warhead into orbit. fly it over the south pole, and attack the USA from the south
this type of weapon system was banned in SALT II, which the USA has not ratified
I predict that post Trump, we are going to have a nuclear arms race with Russia
we should go back to Pershing IIs and aggressively keep Russia out of Latin America
I can see a sea launched version of the Pershing IIs on special launching vessels
then approach to within 500 miles of North Korea (well outside territorial limit), giving them at best 5 min warning time if they launch

All very interesting regarding SALT II.   That said, how is the US going to keep Russia out of Latin America, if Latin Americans have good relations and invite them there?  Why would US wants/interests supersede what individual latin american countries want?   Seems to me that we don't have a right to interfere in their bilateral relationship with Russia or any other country.

You thought 20,000 mph was alien technology. Now you add sea level into the equation? Why?

So,

Are we all ( finally ) agreed that 25,000 MPH at ( near sea level ) isn't possible, yet ?

Or are those using google (and not paying  attention)  going to pretend they're 'correct' ;)

Before Google, people got their info from doing the same thing, reading. Reading books, magazines, or newspapers. Almost everything we learn comes from somebody else. The info we're talking about now just didn't get into our heads when we were born. How we analyze and process info over time shows in our debates whether we did a good job or not. When I stated earlier 25,000 mph is what it takes to escape earths atmosphere, it's what I learned over 30 years ago without the help of Google. Apparently many here did not have the same education, have a lack of education or rejected their education to challenge what I said.

A missile doing 25,000 mph at sea level is possible under specific circumstances and probably has been possible for a number of years. It's simply not been practical or useful.


You're correct it's not practical or useful. It's also a huge waste of resources and our guidance technology isn't good enough to guide something accurately at those speeds. Hypersonic weapons can be a game changer since defenses would be obsolete without needing to go 25,000 mph.

A carrier is at sea level.  A hypersonic rocket travelling horizontally at just above terrain height would explode due to heat build up from air friction long before it ever gets near it's target.  One carrying a nuke would be a danger to the nation firing it.



Hypersonic weapons travel mach 5 and up. America has mach 8 rocket sleds that travel on railways since the 80's at ground level. At that speed, an explosive isn't necessary. The rocket itself would impact with such force it'll disintegrate everything in it's way and make a massive hole through the ship the same way a speeding meteor hits the ground. If America can create products that will not melt at mach speeds and protect a nuke, computers, and passengers, I believe Russia can do it too. They've sent living creatures into space and back without cooking them. Currently America has a projectile heading to the sun to record data. It will be subject to extreme temperatures but the sensitive electronics will survive for most of the journey.

Lasers would be a better choice for near instant targeting, or kinetic accelerator weapons that fire solid inert rounds.   The speed of a kinetic projectile will fall off drastically over any long distance, but would still travel too fast for the capability of any dynamic defensive countermeasures.


Those weapons have been tested by America since the 80's. After over 30 years, they aren't widely adapted since they have flaws. Our carrier groups are designed to kill any delivery system that can shoot projectiles or line of sight weapons such as bullets or lasers at them. Missiles that can go up and down, turn left or right and fly hundreds of miles from their delivery system outside the carrier group's kill range and have a chance to hit a ship but we also have defenses that are designed to take them down when they get close. We don't have a defense for hypersonic missiles at this time. It is a game changer weapon that could make carriers obsolete.

we should go back to Pershing IIs and aggressively keep Russia out of Latin America


Land based nukes aren't important anymore due to subs. America has a sub that carries 24 missiles and each missile has 10 warheads. Park it off the coast of Russia and it can destroy 240 cities in minutes. Can anybody name the top 240 cities in the world, let alone Russia? That's a lot of cities.

Billy,

Your statement 'A rocket has to travel 25,000 mph within the earths atmosphere to escape it.' is simply wrong.

It's right and it's wrong. Without any help in a vertical straight line projectory, Physics says it's right. Gravity slingshot and using the moon's gravity will reduce the need for speed to escape.

I wouldn't get too excited about the Kremlin claim to have a new superweapon.  They do it on a frequent basis.

The US has been involved in Hypersonic vehicles and projectiles for several years. The reason we don't know much about it is because the programs are classified.  Nevertheless, some of the programs have some public information available in news releases.

As noted by some there is a huge difference in the ability to achieve hypersonic speeds within the atmosphere vs. near the edge or in space.

One of the most significant limitations is a characteristic known at Max Q.  The easiest explanation I have seen for non-engineers is in the following link.  It also explains real life examples where we have to throttle down rocket engines until we get past Max Q.   Generally Max Q occurs between 35K and 45K feet above sea level.

The fly in the ointment is Dynamic Pressure.  The faster you go at a specific air density (altitude) the more pressure it puts on the airframe.  Whether it's an airplane or a missile, at some point you can exceed the design and the vehicle will come apart.  Max Q is the point in a missile trajectory that you experience Maximum Dynamic Pressure.

Good morning, Silly BillyB

Why don't you try something called a new year's resolution?

You could start with

I must understand when I've posted BOLLOX and been busted ?

'Ri-ight'

767MPH x 27  = 20,000 MPH within the earth's atmosphere ?

Close to sea level ?

 :ROFL:

so the Kremlin has alien technology ?

Speed record within the earth's atmosphere was 36,000 mph on 2006. This was accomplished by the American Atlas V rocket that uses Russian boosters in the first stage.

http://www.ulalaunch.com/explore/rocket-science/fun-facts

Putin said his hypersonic jet can travel 20,000 mph in the atmosphere. He did not claim it was at sea level. That wasn't in the article but somehow you read it like the many other times you see something that isn't there. 20,000 mph is not alien technology. Also we are not talking world record speeds for manned aircraft. Putin's hypersonic nukes are unmanned which allow them to go much faster and accept more G's during flight.

For decades, Russia's ballistic missiles could travel at high hypersonic speeds under it's own power. That's good for around 50+ miles. The difficult part is getting those same speeds for thousands of miles on it's journey to bomb a city. Hypersonic vehicle gliders is a way to do that and with those enormous speeds, modern defenses would be obsolete.

Funny how some thought Trump throwing away the nuke treaty, increasing military spending, and creating a Space Force were bad things. Putin is actively pursuing technological superiority on military weapons. America can't assume he's not successful. Trump isn't going to let America slip behind.

2tall created this thread in part because he thought you made an idiotic statement. I'm glad you're enjoying it thanking him and putting links in other threads for people to read this. How's the New Years Resolution statement working for you?

I wouldn't get too excited about the Kremlin claim to have a new superweapon.  They do it
on a frequent basis.

At least once a month they have a super-______________ (Enter one of the below here).
Tank, soldier, submarine, aircraft carrier, troop transport, missile, rifle, robot, brain scanner,
computer, laser, ray gun, satellite, force field and then they recycle all of them over again.

While not particularly focused on Hypersonic flight within the atmosphere, I discovered a wealth of information about flight dynamics, targeting and reentry dynamics.  I was surprised to find this published, but assume that the sciences involved must have been well known throughout the academic community for many years.

If anyone thinks it is easy to launch a warhead (of any type) from one continent to another and hit a target while depending fully on internal inertial guidance sensors, take a look at the equations involved in the article.  For decades the USA ICBM missiles have depended fully upon the internal gyros, accelerometers and computer flight program to guide the missile and RV's from liftoff to destination.  That is quite a feat considering that the autonomous system does not require any outside references.  All of the trajectory and targeting constants are loaded prior to liftoff and the flight occurs without any additional outside references.

Inertial reference platforms such as the Gyro Stabilized Platform have always been plagued with issues with drift, calibration errors, vibration induced errors, etc.  The improvements made over the past many decades eventually compensated for these errors and resulted in a guidance system that allows autonomous flight over very long distances with incredibly accuracy at the target destination.

Although not nearly as accurate, the current wave of MEMS Gyros has allowed consumer drones to hover, fly to a destination and maneuver with a pre-programmed flight program.  The future in this field is probably going to open up to a whole world of new applications for inertial guidance.

GPS has added a new element of accuracy to guidance and control and allows for relaxed requirements for the inertial platform.  While it does not affect the consumer, the question remains for military application in our ICBM deterrent force?  If we are faced with a nuclear threat, is the GPS system survivable and do we want to risk depending on it for our response to a nuclear attack?   Perhaps the new "Space Force" has something to do with this assessment.

You bring up food for thought Cal. Imagine we're in a future war and our kids can't go to work because the autonomous vehicles aren't delivering the goods to the plant for the war effort and their cars don't know where to go due to the destruction of satellites. As a nation we can't function. We'll have to get out of our wheelchairs and show the youngsters how to drive using old school primitive methods. Our future military and our society will greatly depend on those satellites out in space. Although the Democrats are laughing at him for his idea, Trump is thinking ahead with the creation of Space Force to protect the devices that will shape our way of life.

France accused Russia of targeting one of their satellites. The destruction of the satellites in order to cripple the eyes of the military and slow down the industrial engine of the enemy will be the first priority in a war.

It's not at all possible to travel anywhere near that speed shooting something
at sea level to something else at sea level, however, it might be entirely possible
to fire something up out into space then turn it back towards the Earth and get
traveling very, very, very fast using the Earths gravity to assist.



Oh Beel,

When you see wack jobs firing AK47's in the air I suppose you think that the bullets fall back as fast, too ?
