Aircraft Thrust

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

Thrust is the force generated by the engine. She pushes the plane through the air stream. The only thing that is opposed to traction is frontal resistance. In a rectilinear horizontally established flight, they are comparatively equal. If the pilot increases traction by adding engine rpm and maintains a constant altitude, the thrust begins to exceed air resistance. The aircraft (aircraft) is accelerated at the same time. Very quickly the resistance increases and again equalizes the thrust. The aircraft stabilizes at a constant high speed. Thrust is one of the most important factors for determining the climb rate of an aircraft, namely how fast the aircraft can climb to a certain height. Vertical speed does not depend on the lift, but on the stock of traction the aircraft possesses.

## 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 WFD (air-jet engine), the tractive force is measured as the result of the mass of gases at the speed difference, namely the speed of the air jet emerging from the engine nozzle and the speed of the incoming air into the engine. Simply put, this speed is equal to the flight speed of a jet engine. The thrust of the WFD is usually measured in tonnes or kilograms. An important qualitative indicator of WFD is its specific thrust. For a turbojet engine, a thrust attributed to a specific unit of air weight that passes through the engine per second. This indicator allows us to understand how high the efficiency of the air in the engine is to generate traction. Specific thrust is measured in kilograms of thrust per 1 kg of air consumed per second. In some cases, another indicator is used, also called the specific thrust, which shows the ratio of the amount of fuel consumed to the thrust force per second. Naturally, the higher the index of the specific thrust of the WFD, the smaller the transverse weight and dimensions 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.

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.
