The Haynes Slipstream Gyro Saucer (HSGS)-711 is an "A" symmetrical, 1/2 rotating, lifting body, circular airframe design which utilizes the SSTO,
VTOL, high beta reentry flight profile. This flying saucer-shaped spacecraft is designed to take off horizontally (or vertically) and climb straight
up into the atmosphere to around 10,000 feet (MSL), using normally-aspirated breathing, low horizontal speed, ramjet techniques.
Two to three miles into the earth's atmosphere the saucer begins to supercharge its two Hybrid ramjet engines to help it climb further (vertically)
into the stratosphere. Flight from the stratosphere to the exosphere is accomplished through the spaceship's oxidizer feed system. Once in the
exosphere it has the option to reduce thrust and float back into a reentry (low beat) profile for the return trip back to earth, or simply accelerate
to earth escape velocity, for orbital space flight establishment.
In the suborbital flight profile, when the spaceship fully enters the earth's atmosphere its hybrid ramjets revert to normal atmospheric
air-breathing operation. From here the flying saucer will continue its vertical descent toward a runway hover approach. Finally, the HSGS will go on
to make an airport terminal area (vertical) landing. The entire sub-orbital flight takes less then 80 minutes to complete, with a weightless hang time
of around 20 minutes. After its initial space flight, the flying saucer is then inspected, refueled and prepared for flight again within a normal
airliner turnaround time frame.
