What is a axial turbine? in aviation.?
138714
There are axial turbines and radial turbines.  In an (aviation) axial turbine, as in a jetliner, there are several stages of air compressors at the intake end and a few stages of turbines at the exhaust end of the jet engine that all rotate on a single axle and the gas therefore passes along the axle from front to rear for axial flow.  In radial turbines (often steam) the steam flows from inside the turbine stage to outside through a circle of blades in a radial direction.  Of course, aviation type axial turbines are often used at land based power plants for peak electrical loads (but with less regard for weight) and power plants use axial steam turbines for major power generation while much smaller radial steam turbines are used for auxiliary equipment loads such as feedwater pumps.

Axial or Normal Stress (denoted by sigma) is equivalent to the force on the beam divided by the cross sectional area that the force is perpendicular to.\n\nThere are other stresses related to different loadings such as shearing stress, stresses from bending moments and a myriad of others. Your question could be more specific.

A turbojet engine is the simplest type of jet engine. It uses the high velocity of the exaust gases to generate thrust\n\nSites regardin Turbojet enhines and their working:\n\nhttp://en.wikipedia.org/wiki/Turbojet\n\nhttp://www.grc.nasa.gov/WWW/K-12//airplane/aturbj.html\n\nA TurboFan engine is the modified form of the turbojet engine. It has a fan in the front which is rotated with the help of a turbine connected to it. The hot exaust gases rotates the turbine which in turn rotates the Fan. The fan in turn pushes the air backwards and generates the major thrust. These type of engines are preffered in high speed passenger aircrafts as they can perform well in high altitudes and are quieter compared to turbojet aircrafts. They are also more fuel efficient than Turbojet aircrafts.\n\nSite regardin Turbofan Engine:\n\nhttp://www.grc.nasa.gov/WWW/K-12/airplane/Animation/turbtyp/etfr.html\n\nThe followin site contains description of diff types of jet engines:\n\nhttp://inventors.about.com/library/inventors/bljetenginetypes.htm\n\nHope this helps

A supercharger (also known as a blower) is an air compressor used to compress air into the cylinders of an internal combustion engine. The additional mass of oxygen that is forced into the cylinders allows the engine to burn more fuel, which improves the volumetric efficiency of the engine and makes it more powerful. A supercharger is powered mechanically by belt- gear- or chain-drive from the engine's crankshaft. It is similar in purpose to the closely related turbocharger, but a turbocharger is powered by the flow of the engine's exhaust gases driving a turbine. Superchargers may absorb as much as a third of the total crankshaft power of the engine, and in many applications are less efficient than turbochargers. In applications where a massive amount of power is more important than any other consideration, such as top-fuel dragsters and vehicles used in tractor pulling competitions, superchargers are extremely common.

An impulse turbine is one where water flows out of a nozzle and hits the turbine blade to give up its kinetic energy.  A "Pelton wheel" is an example of an impulse turbine.\n\nA reaction turbine reacts to the flow of the water past its blades.  It doesn't have a jet nozzle, the turbine is just set in the water flow.  A "Kaplan turbine" is an example of a reaction turbine.

Hydroelectric: moving water from natural or artificial waterfalls powers turbines.\n\nSolar: Special reflective surfaces called photovoltaic convert the sun's radiation into energy, used to power turbines.\n\nWind:  Large turbines are pushed by the movement of the winds; resemble giant windmills.\n\nOil, Natural Gas & Coal (fossil fuels):  Are extracted and burned to power generator turbines.\n\nNuclear (fission): The power of the atom is harnessed as atoms are split apart and the resultant energy used to power turbines; buildings marked by iconic hour-glass-shaped cooling towers.\n\nBiomass: The buring of biologic materials to power turbines.\n\nWaste-to-Energy: the burning of waste materials (such as trash) to power turbines.\n\nNuclear (fussion): Still being developed; fusing atomic nuclei together and capturing the resultant release of energy.

Probably sonic flow of gas relative to leading edges of compressor blades (guess)

A helicopter gets its power from rotors or blades. When its rotors are spinning, a helicopter doesn't look much like an airplane. But the rotor blades have an airfoil shape like the wings of an airplane. So as the rotors turn, air flows more quickly over the tops of the blades than it does below. This creates enough lift for flight.

I cannot immediately give you a perfect answer BUT if you contact one of the manufacturers of wind turbines (a 5 second task with google) then they will almost certainly be happy to give you a LITTLE information from their technical guys.\n\nIncidentally the same works in reverse - which is why aircraft with props only have two blades.\n\nWork was done to find that ONE blade would be best if it could be balanced - hence some very curious looking "helical-style" blades on some BIG experiments wind turbines.\n\nThis is also conditional on a good design for the blades AND a given wind speed. For example, a twin bladed turbine CAN have difficulty starting in VERY low wind levles - when a multi-blade WOULD work. Yet once upto speed, the twin blade or helical blade would be most efficient.

From wikipedia.com:\n\nA supercharger (also known as a blower) is an air compressor used to compress air into the cylinders of an internal combustion engine. The additional mass of oxygen-containing air that is forced into the cylinders improves the volumetric efficiency of the engine which allows the engine to burn more fuel and makes it more powerful. A supercharger can be powered mechanically by belt-, gear- or chain-drive from the engine's crankshaft. It can also be powered by a gas turbine . When a centrifugal type compressor section is mated to a gas turbine drive it is then referred to as a turbo-supercharger, commonly called a turbocharger . Positive displacement Superchargers may absorb as much as a third of the total crankshaft power of the engine, and in many applications are less efficient than turbochargers. In applications where engine response and power is more important than any other consideration, such as top-fuel dragsters and vehicles used in tractor pulling competitions, positive displacement superchargers are extremely common.

Basically, the steam (at pressure) is condensed (little or no pressure) on the far side of the turbine.  The change in pressure causes the steam to flow, pushing the turbine blades.  Steam turbine maintenance is either preventive or repair.  Preventive maintenance is focused on keeping corrosion and wear minimized.  Repairs include rebalancing, replacing rotors, welding to increase worn areas and replacing bearings.

I think....they are called scram jets...

It is normally the additional pressure you get from the turbo. It is dynamic because it changes with turbine rotational speed.

I dont want to copy the entire article from the site---please do visit the link below for full information\n\n\nA wind turbine is a machine for converting the mechanical energy in wind into electrical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator\n\n\n\n\nhttp://en.wikipedia.org/wiki/Wind_turbines\n.\nhttp://www.howstuffworks.com/search.php\nhttp://windpower.getfast.info/wind_power/?kw=small%20wind%20electricity%20systems,wind%20turbine

A turbine is a rotary engine that extracts energy from a fluid flow.\nso how many type of turbine are there now are exactly the same as how many liquids are.\nBasically based of fluids type there are water, gas, steam and wind turbines.\nTurbines are also categorized by another means. You can visit wikipedia.\nHope this help.
