Viper Rocket Trike

"Simplicity is the ultimate sophistication."

      I believe the time is right for a privately owned and operated spacecraft. It will have to be safe, reliable, and inexpensive. The Viper Rocket Trike (RT) is a single place ground launched VTHL rocket glider. It is powered by a pressure fed hydrogen peroxide/polylactic acid (HTP/PLA) hybrid rocket motor. At altitude, it deploys an inflatable paraglider for return to launch site and will have a backup parachute for emergencies. The pilot will experience three minutes of thrust, several minutes of zero gravity, and 14 minutes of glide. The pilot will have full control of the launch, free fall, glide, and landing.

The Viper RT is fueled by polylactic acid (PLA). It is mated to a launcher base in the maintenance hanger. Without the HTP oxidizer, it is relatively safe and can be moved to the launch site by a motorized transport. The HTP is transported to the launch site in a seperate container. Once the Viper RT and launch base are in position and the transporter is removed, the HTP is pumped into the Viper RT. The pilot does a preflight check, climbs into the cockpit, radios for takeoff clearance, and launches.
