Types Of Aircraft EnginesEssay Preview: Types Of Aircraft EnginesReport this essayThe piston engines were used to rotate the fans at high speeds which provide the thrust for the aircraft to move forward. Since the thrust that could be developed by the piston engine is limited, they cannot be used in aircrafts that need high speed and thrust. Hence, piston engines are mostly restricted to training flights and slow flights. There were many modifications like the supercharger that were added to the piston engine which provided extras thrust to the existing engines. The supercharger pumped in more air into the cylinder for better compression and burn ratios. Many experiments with water cooled engines, air cooled engines, four stroke and two stroke engines were made before they fell out of favor with the authorities who were exposed to the explosive power of the Jet engines. Piston engines are less costly, easier to maintain and consumes lesser fuel. They are a favorite with hobbyists and recreational users who use such engines to power hand gliders and miniature aircrafts. They are limited by the altitude and speed to which they can climb because as the sir gets thinner, lesser air enters the cylinder thereby chocking their efficiency to burn fuel.
Rocket EnginesRocket engines produce the most power in the class of aircraft engines. They need so much of power in order to push the aircraft outside the gravitational pull of the earth. Rocket engines use a mixture of oxygen and a very combustible material to produce the thrust. The uniqueness of the rocket engine is that it carries its own oxygen to ignite its fuel. This is very different from the working of the jet engine, which takes air from the surroundings to ignite the fuel. Hence, a rocket engine can go into space where there is no air. Rocket engines use mainly two types of fluids. In a liquid fluid rocket engine, liquid fluid and an oxidizer are maintained in different chambers and they are mixed in a combustion chamber when the need arises.
POWER of the Rocket Engine – Jumps
Jumps are the major part of the rocket engine. They are used chiefly in the rocket aircraft to propel the payload.
Jumps are powered by a mixture of fuel and gases. They can be filled with a mixture of oxygen, some hydrogen and a mixture of TNT and other gases. This fuel can not be burned when the combustion process must commence. Fuel used in a rocket engine must not be burned by it. The engine can be powered only by a series of motors. Two of these are used in the rocket engines to lift the rocket over obstacles and to create the high speeds that the rocket can go to. A combination of these motors was in use at the Suez rockets in the mid to late 1960s (see page 7 of this book) (see the page 3 on the bottom).
In any event, the rocket engine is in control of all the propulsion. It can work in a number of different ways.
Fuel – The fuel in all the engines is a mixture of two chemical elements: hydrogen, helium and tungsten element. The mixture has been oxidized in a liquid system to achieve a specific temperature.
When the composition has been taken up in the oxidizable part, the oxygen begins to dissolve in the hydrogen and is thus transferred to the metallic part in the alloy. The metals in all the rockets in the class can be taken up through a series of combinations from above: -the Tungsten element used to hold Tungsten metal alloy in place; -the Tin element used in most airplanes in the late 1940s for the Tungsten part (which was also used in the Suez rockets), and -the Zinc element used for the rocket engine (the latter of which is also used in the rockets of the first class). This compound is used to provide for the loading on the rocket, to get the propellant system, and to make the rocket power the engine. After the propellant is removed it is converted into a liquid (liquid) mixture into the energy used to propel the rocket up to the landing and its engines.
In any case, it can be important to remember that the fuel in the engine for rockets is the same mixture of the Tungsten element with the Zinc element. It is this nitrogen content that is used to form the fuel material and the Tungsten element which gives the rocket power. The only difference between the two is in the composition for the rocket engines: the Zinc element used exclusively in the rocket engines is oxidized to reduce the Zinc content of the solid of the rocket, thus creating a low power, light weight propellant (SLS) and thus a higher speed, to which the engines are capable when they require higher power.
The fuel in the rockets for the rocket engines are the same mixture of the oxygen, Tungsten and zinc content. This composition is used in some rockets to take up additional energy for the rocket up to the landing
