Because there would only be enough airflow to cool the engine while the aircraft was flying. When the airplane was on the ground before or after takeoff there would not be enough airflow to cool the engine properly.
A free turbine engine is a type of gas turbine engine, where the power turbine and the gas producer turbine are not connected by a solid shaft
Yes, gas turbine is a type of IC engine.
Yes . . .in order to reduce blade vibration and improved airflow characteristics . .
They use both terms. A turbine engine that's being used in an aircraft is a "jet engine," and a turbine engine that's being used in a ground-based application is a "gas turbine." Sometimes it's the same engine--the Lycoming engine used in the CH-47 as a "jet engine" is also used in the M-1 tank as a "gas turbine."

increase airflow around engine, or increase airflow thru air cleaner to engine?
A handle, a pair of pedals, a treadmill, a water mill, a petrol engine, a diesel engine, a wind turbine, a steam turbine, a gas turbine.
The main purpose of the turbine in the turbojet engine is to drive the compressor. The compressor compresses air in the engine to enable it to function.
The difference is what is doing the work, in a gas turbine the turbine spinning does the work and in a piston engine the pistons going up and down moving the crank shaft does the work.
The turbine drives the compressor. The compressor compresses air inside the engine so it can function.
That depends on what you are thinking of. Gas turbine usually refers to all types of jet engines and engines that use the 'jet engine' concept. The turbine engine you are thinking of could be one of a few things, like a jet engine for military aircraft, turboprop, or turbofan for commercial engines.
The Titanic had a Parsons low-pressure turbine that powered the center propeller.
The word is "turbine".
A turbine is connected to a compressor with a shaft. When the hot exhaust gases flow through the turbine, it spins the compressor, which is connected to the air intake, adding pressure and airflow (or "boost") to the intake.
The mass airflow sensor would be between your engine air filter box and the big engine air intake tube
turbine stator (nozzle diaphragm)
They are either powered by a turbine engine like a jet engine or a piston engine.
Numerous problems can cause a hot start on a turbine engine. Erosion of the turbine blades from exposure to the heat of combustion decreases the efficiency of the compressor/turbine combination to move air through the engine. Lack of the proper level starting power, either electricity or compressed air, will not spin the engine at the proper rate, again resulting in lower than needed airflow through the engine. A malfunctioning or out of rig fuel control can schedule the wrong amount of fuel relative to engine parameters. Also, the engine may be operating normally but a damaged thermocouple installation could be giving erroneous temperature indications. On an engine that has an EEC, ECU or FADEC it may be a problem with the computer or one of the parameters that it monitors. This is a fairly thick section in an aircraft troubleshooting guide as the engines have become so complex.
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
