brilliant girl 91 writes; i don't understand the skipping part.
The spaceplane takes off from the equator, flies eastward and skips between the upper atmosphere and space. At the hight of the arc it tips over and goes back down. It turns upwards again when it reaches the atmosphere. It gains speed in the light air and the vacumn. Each skip takes it higher, faster and further. The orbital manoeuvers take 2 hours to complete and the aircraft travels 12000 miles. It uses ordinary jet fuel and liquid oxygen.

A really functional spaceship should be big. It should weigh a million tons. It would have to be a seaplane. Chemical engines can't provide enough range, so the spaceship would have to be nuclear powered. Presently there's isn't a mechanical device to convert nuclear energy into usable thrust. It would have to be invented.

An asteroid could be destoyed with high speed shot. The shot could have a speed of 100,000 MPH and weighs 10.000 tons. A spaceship could carry and launch them..
There could be a fleet of asteroid destroyers. They could take off from onc of the moons that circle Mars., accelerate to a halfway point between, and brake the rest of the way. They could reach the asteroid in a few days.
The missiles are fired one at a time from a point several hundred miles behind the asteroid. This distance is necessary to give the rocket propelled shot time to speed up.
The propellant is used up in a few seconds. The shot has 2 gyro stabilizers, one on the top and one on the side. Each of the gyro stabilizers has a gear that fits into one of 2 gears that run the length of the barrel. As the shot is fired the gears engage and the gyro stabilizers are set in motion.
There's a problem with blowback. Some of it will reach the ship. For that reason the asteroid destroyer is armored and reinforced. It shaped much like a submarine.
The missile is fired from a tube running the length of the ship. The tube is located in the center of the ship. - Richard Kenny

I'm looking for someone with enough money to build a prototype. I suppose it would cost about 5 million $. Please contact me. I'll certainly reply.

respected sir
Ur concept is good,but what about the control surfaces,in a dive from thin air to dense atmosphere there r a lot of chances for instability ,but due to the increase in kinetic energy with dive the control surfaces of the space ship would be inactive,hence it becomes very difficult to control space ship that to at 1500mph in dive,so if stability is taken care then there are less number of chances for failure.
i would like to share lot more things.

Sounds good, very similar to the Concord... like a Concord Plus. How would the switch to liquid oxygen be accomplished? What air tight system would you use to prevent the O2 from venting into the void of space? Would the ship be able to reach the international space station? And what about the car that lost no speed in a 90 degree turn? What kind of car at what speed and in what conditions? Curious!

OK this is not new mate. Several people have worked on these designs back as far as Goddard and Von Braun. What works aerodynamically in the lower atmosphere will rip off on reentry. Thats why the space shuttle flies like a brick and space ship one used white-knight to get it up high. Most jet engines will turn to slag if you throw LOx into it with out another gas. One option is retractable or ducted gas turbine/ram jet that is closed off and a separate rocket kicked in. Several X prize craft were designed to do that. The catch is that the hatch cover gets hotter than most materials can handle and there's a lot of redundant mass and volume.

The skipping is new. The concept spaceship gets lift from it's own kinetic energy. It doesn't get lift from the atmosphere, once it's above 7 miles. It skips through the high atmosphere and vacuum much like an artillery shell with wings and power. Going up and down and up and down. Redirecting it's kinetic energy at the bottom of the dives. Although the air is too thin to support it's weight it's thick enough so that it can change it's direction (climb). The thin air at high speeds has the same effect on the control surfaces as thick air at low speeds.-Richard

One question screams to be answered ---> Even accounting for the shrinking angle of entry (as speed increases) I don't understand how one could use atmospherics to redirect a diving "spaceship" that contains ever higher momentum with less penetration into the atmosphere.
Generally speaking, atmospheric skipping has been used to slow interplanetary craft for orbital capture. The "slingshot" may provide momentum gains, but, does so without introducing atmospheric drag.
Or, are you counting on energy return (like a spring) ? I see your skipping stone as a waste of propulsion (if orbit is your goal).
I have see some interesting concepts for segmented skipping cargo craft, but, I believe the energy for that system was mostly solar collectors & stored EMP discharged against the atmosphere.
Hi Richard
Brian N. Ball's short-story "Escape Velocity" describes a very similar process to what you propose - basically dynamic soaring in the ultra-high atmosphere to steal extra energy from atmospheric motions for the spacecraft. His fictional Skipstones and Moon Shuttles did this trick so effectively that they could fly to the Moon using a relatively small rocket.

Sounds really neat. I haven't read it but I'd like to. Thankyou for writing. -Richard

My concept spaceship is both an aircraft and spaceship. As a spaceship it has gyro-stabilizers and directional jets. With these it can maintain stability in a vacuum or in thin air. Thankyou for writing. Richard Kenny
To ceative
(your question)How would the switch to liquid oxygen be accomplished? What air tight system would you use to prevent the O2 from venting into the void of space?
(my answer)I haven't picked a system as yet. I suppose, some sort of valve would be turned off and another turned on.
(your question)Would the ship be able to reach the international space station?
(my answer)Yes.
(Your question)And what about the car that lost no speed in a 90 degree turn? What kind of car at what speed and in what conditions? Curious!
(my answer)It was a 52 Ford station wagon. I suppose it was sprung in a unique way. I made the 90 degree turns at 70mph. The conditions, at the time, were normal.
Thankyou for writing.-Richard Kenny
You are describing the USAF FDL-7 Hypersonic Glider. Long range gliding is better then "skipping" like Sanger proposed.
You can read more about the FDL-7 now being proposed as a commercial vehicle here.

my concept spaceship isn't at all like the spaceship you described. mine orbits in a single stage and your's in several stages.
Now that is a good idea and something that may be necessary in these coming year!
Hi...Why don'tyou giv out a sketch of your Concept craft!!!..It would be wonderful...to design it

I don't have any drawings because I lack the software to make them.
Do you have such software. You're cartainly welcome to make pictures
of the asteroid destroyer and also my concept spaceship.
To test my theory I would use an ordinary 707 converted to a aircraft/spaceship. It would have fuel tanks for liquid oxygen, gyro-stapilizers, directional jets and a pressure chamber for the crew.
TAKE SPACE SHIP ONE. PUT THE ENGINES ON IT WITH A CAPACITY LIKE A C-130. IN THE MIDDLE A AEROSPIKE LOX ROCKET. TAKE OFF FROM AN AIR PORT. 80,000 HIT THE ROCKET ENJOY EARTH OUTER ORBIT. I AGREE RICH, SINGLE STAGE TO ORBIT CAN BE ACCOMPLISHID RELIABLEY FOR ONLY TENS OF MILLIONS OF DOLLARS. MEN LIKE ME AND YOU HAVE THE VISION. EVERY ONE ELSE HAS THE OPPOSISTION. IM THE GUY WHO WANTS TO BUY SPACE SHUTTLES TO DOCK TO MY BIGALOW AEROSPACE C-3100 AND START THE FIRST FREIGHT COMPANY BETWEEN THE EARTH LEO AND THE MOON LEO. STEELMOON INTERPRISE. CONTACT ME AT STEELMON03@YAHOO.COM MAKE THE SUBJET THE MOON!!
Look like your getting somewhere slowly. Have you heard of the Skylon and its SABRE engine. Its an air breathing engine up to the altitudes your talking about and the airframe is built to hold together at the temperatures and stresses your talking about.
You also should look at nuclear rocketry. A nuclear thermal rocket could propel such a craft to orbit with a long slow burn. Hydrogen is pumped through a reactor producing an ISP of 2000 and low steady thrust like a jet. No oxygen required but is can use an air breathing after burner effect at low altitudes.
A nuclear thermal rocket would reduce the cost to orbit to $300 a kg. Airmail costs more in some places. The catch is no one likes nuclear rockets or reactors flying over their heads. I believe the US government, secretly, has a few nuclear rockets up their sleeve. These ones are not for ground launch but are for intercept and diversion of asteroids. The interceptor and a few fuel tanks would be launched from the ground on a soid rocket stack.
To Wesley
I want to use a 707 to test my theory (see previous text). I don't anticipate any unusual stresses or tempertures.
A practical spaceship/plane would be a seaplane of at least 100,000 tons.

I'll answer your question.
54v_float said; One question screams to be answered ---> Even accounting for the shrinking angle of entry (as speed increases) I don't understand how one could use atmospherics to redirect a diving "spaceship" that contains ever higher momentum with less penetration into the atmosphere.
My answer is.
First of all it has to be going very fast so the control surfaces
can bite into the thin air.
Say the aircft is in the vacuum of space and diving towards the near vacuum. At the bottom of the dive it pulls up and climbs. How did it do this - in air to thin to support its weight? As the stick is pulled back the tail goes down and the bottom portion of the wing is presented to the air. Immediately the plane is deflected from its course and flies a little more upwards and the kemetic energy follows. The kenetic energy stays with the aircraft but a little behind. If it laged way behind, the aircraft would continue to dive, just as you said. The pressure on the bottom of the wing continues to change the flight angle untill the aircraft is climbing again.
Thankyou for writing.-Richard
yeah ! its a nice concept,but you did't say how could we control it from the earth station,and I dont understand skipping !
on may 28th 2010 you left a question, about a spaceplane, on my blog.
write to me and i'll explain it further. you didn't understand the skipping part. it's hard to make another explanation. the first one was supposed to do everything. maybe if you read it again and really visulized it
you could understand it. it skips. it goes up and down. it goes up for awhile and then it tips over and goes back down. it descends to an altitude with enough air to effect the control surfaces and then it goes back up into the vacuum. it makes good speed in the vacuum. it repeats this maneuver untll it reaches orbital speeds. richard
