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 a single place manned ground launched rocket glider. The Viper RT will launch from a ground based launch
site, boost under thrust for 2-3 minutes, coast to an altitude from 25-50 km, reenter, and land on a runway using an inflated paraglider.
Total flight time is about 17 minutes. The mass estimate for the Viper RT is approximately 2400 kg.
