Aircraft Thrust

Link plane. Traction engine aircraft. Thrust of a jet engine.

 

Thrust - the force, worked out motor. She pushes the aircraft through the air. The only thing that resists traction - drag. The straight horizontal steady flight are relatively equal. If the pilot increases the thrust by adding the engine speed and maintains a constant height, traction begins to exceed the resistance of the air. The aircraft (LA) while accelerating. Very quickly, the resistance increases and again calls cravings. LA is stabilized at a constant speed. Link - one of the most important factors for determining the rate of climb of the aircraft, namely how quickly the aircraft can climb to a certain height. Vertical velocity does not depend on the lift and thrust from the stock, which has a plane.

 

Thrust jet aircraft engine

 

Traction force EngineOr a driving force equivalent to all the forces of the air pressure on the inner surface of the power plant. Link some species jet It depends on the speed and altitude. To calculate the thrust of a jet engine is often necessary to determine the traction on the concrete height from the ground, at takeoff and during any speed. For rocket engine thrust equivalent to the mass of the exhaust gas at the rate at which they are emitted from the nozzle of the engine.

For the WFD (jet engine) traction force is measured as a result of the mass of gas to the speed difference, namely the speed of the air stream coming out of the engine nozzle, and the speed of the incoming air to the engine. Simply put, this equates to a rate of speed of the airplane with jet engines. Link WFD is usually measured in tons or kilograms. An important indicator of the quality of the WFD is its specific thrust. For turbojet engine - thrust, referred to a particular unit of weight of air that passes through the engine per second. This indicator allows us to understand how effective the operation of air into the engine to produce thrust. Specific thrust is measured in kilograms of thrust on 1 kg of air consumed per second. In some cases, a different indicator, which is also called specific thrust, showing the ratio of the amount of fuel which is consumed to power for a second rod. Naturally, the higher the specific impulse SRM, the smaller transverse dimensions and weight of the engine itself.

Outside flight or pulling power - a power that uses a jet engine at a particular speed flight. As a rule, measured in horsepower. The size of the frontal thrust indicates the degree of constructive optimum jet engine. The frontal thrust - a ratio of the largest cross-sectional area index to pull. The frontal thrust is thrust in kg divided by the area in square meters.

Aircraft Thrust force

In the world of aviation the most prized engine, which has a high frontal thrust.

The more perfect the WFD in constructive terms, the smaller the rate of its specific weight, namely, the total weight of the engine together with the devices and service units, divided by the value of its own power.

Jet engines as thermal generally differ from one another not only in power, weight, thrust, and other indicators. In evaluating WFD play a great role parameters that depend on the efficiency of their own, notably the COP (coefficient of performance). Among these indicators is considered to be the main remote fuel rods to a specific unit. It is expressed in kilograms of fuel which is consumed in an hour on the formation of one kilogram of thrust.
