A typicial Auxiliary Power Unit (APU) is a turboshaftengine. It is similar to a jet engine with how it's compressor and turbine sections are laid out. However jet engines provide power through thrust (exhaust gas pressure) whereas turboshaft engines provide power through a shaft attached to either the compressor or turbine section.

What is difference between a rocket a jet engine?
A rocket explodes and a jet doesnt.
What is the difference between a jet engine and a rocket engine in relations to oxygen?
A jet engine takes oxygen from the air to burn with its fuel. A rocket engine has to take oxygen or some comparable oxidizer with it.
Difference between the thermal jet engines and the chemical rocket engine?
dnt knw
What makes an aircraft jet engine start?
APU turns it over. These used to be on external cart on early jets but are now internal.
What is the difference between water loom and air jet loom?
difference between air jet loom and water jet loom
What is the difference between a jet plane and a propeller?
A jet plane uses a jet engine's thrust for propulsion. A propeller is a set of blades somewhat like a big fan that blows air to the back of the plane for thrust instead of using a jet engine for the thrust to move the plane forward.
What source of electicity do planes have?
Almost all aircraft engines have generators. Most large aircraft also have an APU (small jet engine) specifically for providing extra electrical power.
What is the exhaust pipe on the rear of the Boeing 737 and 747 fuselage for?
On the very rear of the fuselage of the B747 is a round exhaust for the Auxillary Power Unit(APU). Every large passenger aircraft has an APU that is used to provide electrical & hydraulic power to the aircraft while it is on the ground (or also in the air during an emergency). The APU is a small jet engine that runs off the same fuel as the jet engines that provide thrust to the aircraft. The Wikipedia link shows a view of the APU exhaust and a view of the engine.

What is the difference between jet black and black?
The 'jet' in jet black refers to the mineral which is a black colour.
How do jet engines provide a forward thrust to for an airplane?
The thrust is given by the difference in the velocity of air coming into the jet engine and going out of the jet engine, Thrust = F= mdV/dt = ma.
What is the difference between airbus and jet plane?
