How does a PT6 engine work?

There are three parts to the PT6 engine. First is the compressor section. It's like any other turbine engine. Next is the "free power turbine." You have seen the little pinwheels kids like--you blow on them and they spin. Well, this is a pinwheel for grown-ups: there's a fan on the end of the compressor section's shaft. It blows air against a second turbine that's attached to the next section, which is the gearbox. When the second turbine spins... the gears and shafts in the gearbox turn and make the engine's propeller rotate. The PT6 is an unusual engine in that it's "in backwards"--the intake end of the engine, which in most engines points toward the nose of the plane, points toward the tail on a plane with a PT6 in it. PT6 engines are very versatile and have been used for a lot of things. Someone even tried running a locomotive on one--it worked fine but railroad mechanics would need to be retrained to work on jet engines, so the experiment never got past the trial stage.


How a helicopter engine works?

In a very similar way to ordinary aero engine. There are internal combustion engines which work on the induction, compression, power and exhaust system, linked through a gearbox to a shaft which drives the prop. Or the jet version which works by hot gases turning a turbine, which has a shaft running through the middle, again linked through a gearbox to a shaft which drives the prop. This is called a turboprop.


What engine operates using a three sided metal rotor instead of the traditional piston and cylinder arrangement?

The three sided rotary engine is a Wankel engine. The engines were used in Mazda cars, as well as some Norton motorcycles.


What is a reciprocating triple expansion steam engine?

A reciprocating triple expansion steam engine is a type of steam engine that uses three cylinders, each operating at progressively higher pressures to extract energy from steam. The steam expands in three stages, which allows for more efficient energy conversion compared to single or double expansion engines. This design increases the engine's efficiency and power output, making it suitable for large applications, such as ships and power plants. The engine operates by converting the thermal energy of steam into mechanical work through the reciprocating motion of pistons.


What hammer is most used by mechanics?

A a field mechanic dealing with diesel engines the hammer I use most often is a three pound/ 1.5 kilo drillers hammer. It has a very short handle which allows me to swing it in tight spaces The second a ball pien hammer.
