The Lockheed Martin X-33 was a proposed uncrewed, sub-scale technology demonstrator suborbital spaceplane that was developed for a period in the 1990s. The X-33 was a technology demonstrator for the VentureStar orbital spaceplane, which was planned to be a next-generation, commercially operated reusable launch vehicle .
The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum. [ 2 ] Like all early Gnome et Rhône engines the Omega features a single pushrod driven exhaust valve on the cylinder head; the intake valve is located in the piston crown, opening by inertia on the downstroke and feeding the intake ...
The Gnome 7 Lambda was a French designed, seven-cylinder, air-cooled rotary aero engine that was produced under license in Britain and Germany. Powering several World War I-era aircraft types it was claimed to produce 80 horsepower (60 kW) from its capacity of 12 litres (730 cubic inches) although recorded figures are lower.

They soon started development of one of the first purpose-designed aircraft engines, combining several Gnome cylinders into a rotary engine. The design emerged in the spring of 1909 as the 7-cylinder rotary Gnome Omega, delivering 50 hp (37 kW) from 75 kg. More than 1,700 of these engines would be built in France, along with license-built ...
The original engine was a 50 hp (37 kW) 4-cylinder inline water-cooled Vivinus. [2] Farman replaced the engine with the new and more reliable 50 hp (37 kW) Gnome Omega rotary engine while the aircraft was at the Grande Semaine d'Aviation at Reims, and the new engine's reliability contributed towards his success there. The aircraft had been ...

LASRE was a small, half-span model of the X-33's lifting body with eight thrust cells of an aerospike engine, rotated 90 degrees and mounted on the back of a Lockheed SR-71 Blackbird aircraft, to operate like a kind of "flying wind tunnel." The experiment focused on determining how a reusable launch vehicle's engine plume would affect the ...
