Development of XLR11 rocket engine began in 1944 at Reaction Motors, Inc. A rocket engine is a Jet engine that uses only Propellant mass for forming its high speed propulsive jet. Year 1944 ( MCMXLIV) was a Leap year starting on Saturday (link will display full calendar of the Gregorian calendar.
Each of the four combustion chambers produced 1500 lbf (6. A combustion chamber is the part of an Engine in which Fuel is burned 7 kN) of thrust. Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws. The engine was not throttleable but each chamber could be turned on and off individually. A throttle is the mechanism by which the flow of a fluid is managed by constriction or obstruction
The XLR11 was used in the Bell X-1, the Dryden lifting bodies and other vehicles. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The Dryden Flight Research Center (DFRC located inside Edwards Air Force Base, is an aeronautical research center operated by NASA. The lifting body is an Aircraft configuration where the body itself produces lift.
For early tests the North American X-15 was powered by two XLR11s. These engines were boosted to 2000 lbf (8. 9 kN) of thrust per chamber for a total of 16,000 lbf. Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws. In comparison, the idle thrust of the X-15's XLR99 engine was 15,000 lbf. The XLR99 engine was the first large Throttleable restartable liquid propellant Rocket engine.
