If the pilot wants to trim the fly at h = 30.000 ft with V-800 fps, what are d·E, and T required? 2. If h = 2,000 ft, and V = 400 fps, determine , and T. Assime that the air density can be determined by 0.0023769(1-6.8743929 × 10-%)'.372137 0.0006813 exp[-3.693018 × 10-5(h-36, 089)], if if h 36.089 p(h) = where is in slug/ft" and h is in ft.Explanation / Answer
1.) An engine which takes air in from its front area and pushes air out from the back area is called an Air breathing engine. The air taken in is used for the burning of fuels, that is these engines are internal combustion engines. The air sucked in is first compressed and then it mixes with the fuel and get ignited. This helps in the working of the engine and the expelled air is the exhaust gas.
The major classification of air breathing engines are based on the way they are powered.
When powered by gas turbine :
Ram powered ramjet and scram jet engines , pulsed combustion jet engines such as motor jet and pulse jet engines are also types of air breathing engines.
2) Gas generators are devices used for generating gas either from chemical reactions or solid/liquid source. Gases are not preferred to be stored when they are pressurized, in these conditions gas generators are mostly preferred. Generation of gaseous chemicals in industries is a major application of gas generators.they are used to power turbo pumps . Used to convert coke to producer gas. Used as a power source in rockets . Hydrogen peroxide gas is made using the gas generator which in turn is used for rocket propulsion. Also used for oxygen generation.
