Scaled: Good Sep, Good Handling
SpaceshipOne flew for the first time on Friday, gliding
to Earth after being released by its mothership, White
Knight. Pilot Mike Melvill said the flight was as advertised.
Separation from White Knight at 47,000 was described as
"clean and positive." Melvill also said the spacecraft, Burt
Rutan's entry into the X-Prize Contest, handled very much like it
did in computer simulations.
Scaled Composites Flight Test Report:
Flight 30L / 03G-1
Date: 7-Aug-03 Flight Time: 1.1 hours / 19
minutes
White Knight Pilot: Binnie Copilot:
Bird
SpaceShipOne Pilot: Melvill
Objectives; First glide flight of SpaceShipOne.
Results:
The space ship was launched at 47,000 feet and 105 knots, 10 nm
east of Mojave. Separation was clean and positive with no tendency
to roll off or pitch bobble. An initial handling qualities
evaluation was very positive, supported close correlation to the
vehicle simulator and with that confidence, the first flight test
cards were executed as planned.
The flight provided handling quality and performance data over
60% of the expected subsonic flight envelope from stall to 150
knots. Trim sensitivity, stick forces, control harmony and L/D
performance were all as expected. The on-board avionics and energy
management cueing displays performed flawlessly, the gear extension
rapid, and the vehicle made a smooth touchdown at 7:56 local on
Runway 30 at Mojave.
The entire flight, from launch to landing, was viewable from the
ground and SpaceShipOne with its unique planform was
intriguing to watch as it cut gracefully through the air and was
put through its paces.
