What is the torque of one engine on a 747?
Jet engine power ratings are generally in terms of thrust, not torque. The 747 has undergone several engine redesigns. The Pratt & Whitney JT9D engine series varies from a maximum thrust of 46,300 to 50,000 lbf.
What is thrust specific fuel consumption of turbo shaft?
There is no such thing as thrust specific fuel consumption of a turboshaft engine, as a turboshaft is designed to deliver mechanical power, not thrust. This mechanical power can be converted into electric power by a generator or converted into thrust by a propeller or rotor. Basically, a turboshaft uses jet technology but is an alternative to a piston engine. While thrust specific fuel consumption doesn't exist for a turboshaft, "brake specific fuel consumption" does. It measures the rate of flow of fuel required for a certain amount of power. For example, a specific fuel consumption of 0.2 lbs/h/hp means that for every horsepower the turboshaft produces, it burns 0.2 lbs of fuel each hour.
Which gear type does not have axial thrust?
herring bone gear (Double helical ) doesn't axial thrust
How aircraft engine function?
with jet propulsion, Air is taken in at the front, than compressed by an compressor. Fuel is added tot the air and ignites. This drives the temperature higher, making the air expand and increase the pressure. After that a turbine takes some of the energy of the flow, decreasing the temperature and pressure and converts the energy into work. the work than is used to power the compressor. The exhaust provides a thrust for the airplane. with a propeller, an engine drives a propeller which provides thrust for the airplane
What is bypass ratio in gas turbine engine?
bypass ratio im an early singlr or twin-spool bypass engine is the ratio of cool air mass flow passed through the bypass duct to the air mass flow passed the high pressure system. Bypass ratio for the fan ducted bypass engine is the ratio of total air mass flow through the air fan stage to the air mass flow that passes through the turbine section/high pressure(engine core) system.A high bypass ratio i.e 5:1 is usually common with ducted fan engine.
What is the relation between net thrust and gross thrust in a ramjet engine?
Net thrust in a ramjet engine is the actual useful thrust generated for propulsion, while gross thrust is the total thrust including the contributions from ram pressure. The net thrust is the difference between the gross thrust and the drag of the engine itself. The net thrust determines the actual propulsion force available for moving the aircraft forward.
When are the 4 forces of flight equal?
The four forces of flight (thrust, lift, weight, and drag) are equal in level flight when the aircraft is maintaining a constant speed and altitude.
What is engine thrust?
Thrust is the amount of power generated by the engine.
What is the horsepower of one engine in a Boeing 737?
This is the pure speculation. It is to imagine a piston engine and a propeller which would give same thrust as B737 jet engine. With B737 speed of 0.8 M at altitude and maximum attainable efficacy of a propeller (notwhistanding compressibility effects), for B737 engine (one engine) thrust of 8,400 to 11,300 kg, the Power would be from 32,000 to 43,500 HP per engine !

Where does a gas turbine engine get its best thrust specific fuel consumption?
I think it happens because of the altitude and the fuel burn rate get slower as they clam higher 10,000 fleet
What provides the force for thrust?
The engine provides force for thrust.
Does thrust effect a paper airplanes?
An arm throwing it is causing the thrust.
What are the forces on an airplane?
There are four forces that act on an airplane that keeps it at a level altitude. Thrust, drag, weight, and lift determine whether a pilot flies at a level altitude.
What causes the thrust of an airplane?
The engine causes thrust, it moves the aircraft.
Forces on steady speed on plane?
When a plane is flying at a steady speed, the forces acting on it are balanced. The main forces involved are thrust (from the engines), drag (air resistance), lift (from the wings), and weight (gravity pulling the plane down). These forces work together to keep the plane moving at a constant speed and altitude.
An airplane flies at constant speed in a horizontal straight path in other words the flying plane is in equilibrium two horizontal forces act on the plane one is the thrust of the propellers that push?
The thrust from the propellers provides the forward force needed to overcome the drag and maintain a constant speed. The lift generated by the wings counters the force of gravity to keep the plane at a constant altitude. As long as these forces are balanced, the plane will continue to fly in a straight path at a constant speed.
What is a difference between turbojet engine and piston engine?
I think your question is self explanatory. A piston engine develops thrust by using pistons. The turbojet engine develops thrust by rotating a turbine. Here both piston and turbine are means of converting thermal energy to mechanical energy. For the piston engine the thermal energy resulted from combustion at constant volume is used to push down the pistons which in turn rotate a shaft. For the turbojet engine(more precisely gas-turbine engine) the thermal energy resulted from the combustion at constant pressure is used to rotate a turbine which is connected to a shaft.
