Open cycle arrangement of a gas turbine?
1. The working gas is compressed in compressor and directed towards the heat exchanger (Air heater), where heat is being added to the compressed gas before it enters the turbine. 2. The heat is supplied by an external source such as a nuclear reactor, or some other heat source. 3. The hot gasses then expend and accelerate through a nozzle which drive the guide vanes of the turbine and then shaft. 4. At last, the remaining exhaust gasses pass through a cooler and directed towards the compressor inlet.
How does a turboprop work?
A simple turbine.Air is drawn into the engine continuously and compressed by a series of rotating blades. Fuel is sprayed into the combustion chamber and burnt increasing the gas temperature to around 1200C.The hot high pressure gas expands through a second set of blades mounted on the same shaft as the compressor blades. The energy of the gas is partially expended powering the compressor, but has a residual energy which is either expended as a hot jet (resulting in thrust) or which drives a further independent set of blades to power a propeller or other device.see http://www.rolls-royce.com/education/schools/how_things_work/journey02/index.html
What is the Difference between a turbine blade and a compressor blade?
A turbine is a machine that has a rotor of some sort that spins as a reaction to the flow of a fluid of some kind. A generator can be one of may things, but we often associate that term to a piece of equipment that converts mechanical energy into electromagnetic energy, or electricity. That said, the turbine could be connected to the generator to produce electricity from mechanical energy. The turbine is all about mechanical energy, and the generator converts mechanical energy into electric energy.
What is the difference between steam turbine and water turbine?
The difference is that geysers are way much hotter than the steam from hot springs. The geysers can give you 3rd degree burns. But so can the steam from hot springs if you're in there to long.
What is a gas turbine cooled by?
It depends on the type of engine, but its generally one of a few things. A turbofan like on a commercial plane have the bypass, or large amounts of air flowing close to the out side of the engine. A higher temperature engine may have a heat exchanger on the turbine blades that actuall takes cooler air and passes it over the vanes so they don't melt. Almost every turbine engine has some sort of oil cooler to help keep the moving parts from getting too hot. With many turbines the idea is to more or less protect the engine from heat than to cool it down. More heat with a turbine means more power.
What is high pressure compressor in turbine engine?
In an axial flow turbo fan engine there are two compressors. The first compressor is the low pressure compressor or it can also be referred to as the fan and is the first rotating assembly in the engine located aft of the engine inlet. The second rotating assembly located aft of the low pressure compressor or fan is the high pressure compressor. The basic difference between the low and high pressure assemblies is the amount of air pressure they generate. Low pressure compressors usually have a small number of stages and fewer and larger blades. Whereas the high pressure section has more stages and smaller blades. As the air passes through each stage of the compressors it is squeezed thus the pressure and temperature increase. When the air flow exits the high pressure compressor it is at its highest temperature and pressure generated by the cold section (compressor section) of the engine. Hot section/combustion section is another matter. Keep in mind that there are numerous turbo fan/turbine engines and each one probably will be configured differently as far as the number of stages and blades in each compressor section.
What is the explanation for the operation of the turboprop?
A turboprop engine is basically a turbojet, but with a propeller connected to the shaft. Air flows in the engine, is compressed by the compressor blades, and is ignited in the combustion chamber. the resulting jet of hot gas turns the turbine blades and shoots out the exhausts. A gearbox and propeller is connected to the central shaft. The turbine and compressor blades are connected to the central shaft. When the turbine blades turn, they turn the shaft, turning the compressor and the propeller. Most of a turboprop's power comes from the propeller.
How does 300zx turbo work?
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.
What causes hot start in turbine 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.
What is the hot secion of a jet engine?
The hot section is the combustion area of the engine located in the aft section before augmentation.
What are turbochargers and superchargers?
Turbo and superchargers are examples of heat turbines used to compress and pressurize intake air charges for higher power outputs. A turbocharger uses the heat energy from exhaust gases to drive its turbine. In comparison a supercharger uses the mechanical energy of the motor through the drive belt system to run its turbine. A supercharger produces parasitic power and fuel efficiency losses through this set-up. For these reasons a turbocharger has higher efficiency.
Is air condition discharge hot to the touch?
Yes, the discharge line from the compressor can be hot.Yes, the discharge line from the compressor can be hot.

Why does the AC on a 2000 Monte Carlo make a groaning noise from the engine bay when driving on hot days?
Maybe a bearing in the compressor
A source of warm water is called a?
Turbine
Why is there a whistling sound in the twin turbo diesel engine of a 2011 land cruiser?
The whistling sound is the turbochargers at work.. The turbines inside the turbos creates the whistling sound as the exhaust gasses pass by each blade of the hot turbine and the cold turbine blades drive air into the engine.
What is the TBO on a pt6-112 engine?
