Thrust is the main propulsion medium. The jet engines produce the thrust (the force forward) the air moves across the top of the wings creating a vacuum which in effect hold the aircraft in flight. The greater the engines are worked the greater the thrust and therefore speed.

How is it that rockets can go into space but jet airplanes cannot?
Jet engines require oxygen to burn their fuel. When a jet gets to extremely high altitude, it is difficult to get enough air into the engine to keep the engines going. The limit for turbojets is about 40km. Ramjets can (theoretically) operate up to 75km altitude, but efficiency drops off above Mach 5 (1.5 km/s), which is far less than the escape velocity (11.2 km/s). A rocket, on the other hand, carries oxidizer as well as fuel. It can continue to operate even when it gets above most of the atmosphere. Rocket engines also have much higher thrust-to-weight ratio.
How many engine cylinder used in helecopter?
NONE all modern helicopters use jet turbine engines. if you look at older helicopters, they suddenly changed from lattice construction with one or two people on board to multi-occupancy solid bodied ones. this is when most manufacturers changed from piston to jet engines (during the vietnam war it was noticeable (watch old episodes of mash or the film apocalypse now) a few very small and self-build helicopters still use piston engines and are generaly 4 to 8 cylinders... the problem is they're relatively low powered compared to jet turbines and massively heavier.
What fire engines were used on Heartbeat?
carburetor
Is it possible to power a rocket using nuclear power?
Yes it is and NASA have various designs and projects to study the practicalities of such engines. Nuclear power may be used to heat a propellant, provide an electrical power source for an ion engine, or may be used directly to provide thrust in a number of ways, one example being the fission-fragment rocket.
What is a propeller?
It is a power-driven shaft with radiating blades that are placed so as to thrust air or water in a desired direction when spun by an engine. Propellers are used to drive an aircraft or boat forwards (or when used in reverse, backwards).
Why jet engines are used at high altitudes?
For thrust. Engines are used to overcome the drag of the airplane.
Which of the forces is directly provided from jet engines?
Thrust
What do jet engines create a great deal of?
Thrust .. and noise
How do jet planes fly?
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
How much is 33000 pound of thrust?
33,000 pounds of thrust is equivalent to a force of 146.9 kilonewtons. This amount of thrust is commonly used as a unit of measurement for the power of jet engines and rockets.
How much power do jet engines produce?
Earlier jet engines like the the Pratt & Whitney JT8D used on the B727, B737, DC-9, etc. produced thrust in the 12,000 to 18,000 pound range. (A pound of thrust is equal to a force needed to accelerate 1 pound 32 feet per second per second.) Newer jet engines like the Rolls Royce and GE engines used on the B787, A380, etc., are capable of producing thrust in the the 65,000 to 80,000 pound plus range.
What is the term for powering airplane engines?
Jet engines produce thrust. All others produce horsepower.
What are the two types of engines used in planes?
The two main types of engines used in planes are piston engines and jet engines. Piston engines, similar to those found in cars, use reciprocating motion to generate thrust and are typically found in smaller aircraft. Jet engines, on the other hand, utilize the principle of jet propulsion, where air is compressed and mixed with fuel to produce thrust, making them suitable for larger, faster aircraft. Each type is suited to different flight requirements and operational environments.
Is thrust measured with newtons?
Yes. Any unit of force can be used to indicate the amount of thrust.
What is the Jet Engine's purpose?
The Jet engines purpose is to create thrust.With out Thrust a plane would not be able to fly.
How are breaks applied in jet engines?
A jet engine has no brakes. Though they do have thrust reversers which change the direction of thrust to slow the aircraft down. Aeroplanes have brakes on the wheels.
How do jet engines provide a forward thrust for an airplane by using the continuity Equation?
they move
