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.
the steam engine was quicker and stronger than hoses
Same as a regular car engine but to give it the extra power it has some more cylinders
a machine that transforms heat into machanical energy, or work
Before the steam engine, the best one could hope for machines in work was wind- or water-mills. The steam engine generated much greater power, allowing not only more reliable results, but longer distances on which that energy could be used.
No engine is 100% efficient: there is always some loss of energy between input and output.
3600 hours with a hot section inspection at 1800 hours.
There are many different versions of Cessna aircraft. Many of the smaller ones use a version of the Lycoming 360, a flat 4 gas engine. Some of the larger ones use a PT6 A turboprop.

Buying a used PT6 engine can be a cost-effective option, but it requires careful evaluation to ensure you're getting a reliable and efficient engine. Here are the key factors to consider before making a purchase: Total Time Since New (TTSN) & Time Between Overhaul (TBO) TTSN (Total Time Since New): Indicates the overall wear and tear on the engine. A lower TTSN usually means a longer lifespan. TBO (Time Between Overhaul): PT6 engines typically have a TBO of 3,000 to 6,000 hours depending on the model and operation. If the engine is near its TBO, factor in the cost of an overhaul. Tip: Engines closer to TBO may seem cheaper but could require a costly overhaul soon. Maintenance & Overhaul History Review logbooks and maintenance records to verify the engine has been properly maintained. Look for compliance with Pratt & Whitney Canada (P&WC) service bulletins and airworthiness directives (ADs). Check if the engine has had any major repairs, part replacements, or previous incidents (e.g., foreign object damage or hot starts). Tip: A well-documented maintenance history is a strong indicator of engine reliability. Hot Section Inspection (HSI) Condition The Hot Section Inspection (HSI) assesses the condition of critical components like the compressor turbine, power turbine, and combustion chamber. If an HSI is due soon, factor that into the purchase cost. Tip: Request the latest HSI report to check for excessive wear or damage. Engine Cycle Count PT6 engines have cycle limits on certain components (e.g., compressor and turbine blades). High cycle counts can mean parts will need to be replaced sooner, increasing costs. Tip: Choose an engine with a cycle count that allows for extended future use. Engine Modifications & Configuration Some PT6 models have performance upgrades (e.g., enhanced compressor or fuel nozzles). Ensure the engine configuration matches your aircraft's certification and operational needs. Tip: Modifications can increase efficiency but should be FAA/EASA-approved and compatible with your aircraft.
that the engine has nitro power which goes to the engine. when the engine receives the signal the engine starts to work
The Cessna 406 first flew in 1983. It is a twin turboprop 14 seat executive aircraft with 2 PT6-A engines. ( It is NOT a "bushplane" as described in the popular youth book ,"Hatchet" )
The 406 is a high speed executive aircraft that seats12-14 people. It has 2 Pratt and Whitney PT6-A engines and can fly at up to 300 mph and 30,000 feet high.
Noise. Without noise, it can't work. Noise is in an engine, and without it does not work. Every engine has to make some kind of noise, internal or external, inside or outside the engine.
yes. it should work fine.
The amount of work done by a heat engine equals the difference between the heat input and the heat output of the engine. This is known as the heat engine's thermal efficiency.

A rotax engine works on smoke, when the smoke comes out it doesnt work anymore!
