Lucky Seven
American manned spacecraft. Study 2004. X-Prize suborbital ballistic spacecraft concept of Acceleration Engineering, Bath, Michigan.

Lucky Seven was a design of Mickey Badgero of Acceleration Engineering, Bath, Michigan. The concept used rocket-powered vertical takeoff launch and parafoil landing. Lucky Seven was to be a conical rocket 9 meters long and 3 meters between fin tips. For launch and landing, the rocket was to be supported on four fixed leg-fins, each 1.5 m tall. These legs were part of a metal frame that supported the propulsion system, a pressurized cabin, and a nose cone/recovery system. Launching vertically, the main engine, a pressure-fed, liquid oxygen/liquid methane design , was to burn for 90 seconds, after which the rocket was to coast for another 100 seconds past the 100-kilometre altitude mark. Passengers were to experience weightlessness for about three and a half minutes. Upon re-entering the atmosphere, a drogue parachute was to be deployed to slow the ascent. When the air thickened, a parafoil was to be deployed. The spacecraft was to then return to the launch site, using a Global Positioning System satellite guidance system, gliding to a vertical landing.

Height: 9.00 m (29.50 ft).
Span: 3.00 m (9.80 ft).

  • X-Prize The X-Prize competition was an attempt to promote commercial civilian spaceflight in a manner similar to the prizes handed out in the early days of aviation. Ten million dollars was to go to the first team to fly a vehicle capable of launching three people into space (defined as an altitude of 100 km in a suborbital trajectory), twice in a two-week period. The vehicle had to be 90% reusable by dry mass. For purposes of the two flights, the competition accepted flight by one person and ballast equivalent to two others at 90 kg per passenger. More...
