Avg score: 0% Most missed: “What causes thrust of an engine?”
Thrust is the force applied to an aircraft in the direction of flight. Jet engines produce thrust by: Mixing fuel with oxygen or another oxidizer in a combustion chamber Igniting the mixture Creating hot, expanding gases Using the expanding gases to produce thrust directly  Jet engines produce thrust in a similar way to the engine/propeller combination. Both propel the aircraft by thrusting a large weight of air backwards: One in the form of a large air slipstream at comparatively low speed The other in the form of a jet of gas at very high speed  Jet engines commonly develop 9,900...
