VTVL technology demonstrator From Wikipedia, the free encyclopedia
In rocketry, the Armadillo Aerospace Quad vehicle called Pixel is a computer-controlled VTVL rocket that was used in 2006 to compete in the Lunar Lander Challenge.[1]

The quad vehicle design is a pressure fed in blow-down[clarification needed] mode from an initial pressure of 320 psi for level 1 (400 psi level 2).[citation needed] The cold gas vernier engines are cross-fed by gas drawn from ullage space of the opposite tank. The vehicle was able to transfer propellant through connecting pipes between opposite tanks by controlling ullage pressures with the thrusters; this helps it balance, minimizing gas use. The main engine had two-axis thrust vectoring.[citation needed] The vehicle was fully computer controlled; with guidance from GPS and fiber optic gyros.

On 8 March 2010, Matthew Ross of Armadillo Aerospace confirmed that Pixel had been converted to methane/LOX propellant and sold to NASA as part of the Project M testbed for the Autonomous Landing Hazard Avoidance Technology (ALHAT) LIDAR range finding system under development by Jet Propulsion Laboratory (JPL).[2]
