The ability of flying
:Engine generates the ability to fly the
plane. Planes uses three main types of engines
reciprocating or piston engines-
Jet
engines-
rocket engines-
reciprocating engines are the most weight
and least productive of the ability of these types, while the rocket engine is the most productive capacity
:Comparison of aircraft reciprocating engines and jet
engine
uses more
than other types of aircraft engines.Most small aircraft and many of the
large aircraft fitted with reciprocating engines.For these aircraft there is
one propeller or more. the engine runs aircraft fan, the power generated
to push the plane in the air
piston engines in the plane are similar to his work in the
car. In both cases, the engine burning a mixture of gasoline and air
inside the cylinder, causing an explosion which causes pushing the piston up
and down inside the cylinder to manages crankshaft, , which makes the plane
fan rotate. In the car the
crankshaft push other parts eventually lead to the rotation of the
wheels. aircraft engines uses a device called Amonat instead of
batteries to make a spark. most of the aircraft engine is cooled by air instead of water
the ability of reciprocating engine Measured
by unit of kW , capacity of most aircraft engines is ranging between 22 kW
for small & single engine aircraft and 300 kW for two large engines
aircraft . the most productive of the reciprocating engines used to
drive the capacity of aircraft was the engine is installed on the giant
American bomber B-36, which was
generating 2722 kW, in the late forties of the twentieth century. No
longer large aircraft use of such reciprocating engines with a high
capacity. Such aircraft are pushed by automatically jet engines lighter
than reciprocating engines, although they generate a lot power to them
Reciprocating engines still
used in most light aircraft which works better than the jet engines at low
speed
:Jet
engines
jet engines enable large aircraft to travel long distances at
high speeds. But jet engines must also have that work satisfactorily
even at low speeds used for automatic pushing for safety landing
:There are three types of jet engines, are
turbo-jet engine -
turbine fan engine -
Turboprop and turbo shaft -
jet engine turbine is the first success engine , some aircraft is
still used it till now . turbo jet engine pulls air from front of it to
burn it after mixing with fuel. this process generates a powerful
exhaust gas which blown through the engine with high speed, causing the
engine to move forward at high speed is equal. Before exhaust is
leaving the engine nozzle , it runs a
turbine disk to run various turbine engine parts
all modern airliners are nearly provided
turbine fan engines which are similar
to turbo-jet engines with some improvements. The turbofan works
in most cases, like turbine jet engine, but it has a front fan pulls a large
amount of air. Moving only a portion of this air for combustion with the
fuel to generate exhaust puffs , the
rest of air joins the exhaust gas when
they came out together from the barrel of the engine. the exhaust is
becoming more capable and less heat
than the exhaust of turbine jet engine .. turbofan engine consumes less
fuel than jet turbine engine, produces less noise, and it works better at
slow speeds
turbo-propeller engine uses to push the front. Gathering
the surpassing power of the engine turbo-jet and the best ability of fans on
flying at low speeds
There are other types of jet engines, but they are rarely
used to push the aircraft. compressor Turbine jet is the simplest types of
jet engines and most of the productive capacity. But it only works at
high speeds only. The compressor
jet engine is used mainly to push aircraft missiles (the drones), as
well as weapons. Pulse detonation engine is also
simplified. However, it consumes a great quantity of fuel and noisy
which makes it not fit to push the
aircraft
Rocket
engine. Rocket engine works in a similar manner to the jet engine work ,
except that it does not need to supply oxygen from the outside air. it
improves missile engine performance at very high speeds, but it also consumes
a high degree of fuel raising the cost of operation. also the
possibility of missile engine explosion at any moment is a reason not to use
it for the automatic push for the passengers aircraft becuase of the intensity of gravity
Although its Disadvantages , the rocket
engine is sometimes used to push for the aircraft. There are a few of
the jet or turboprop engines that use a small rocket engine to help it take
off at high speed if the cargo is large or taking off from a short
runway. Rocket engines fixed either the body of the aircraft or the
bottom of their wings. Rocket motors have been used to push for many of
the automated aircraft test, ultrasound, such as the Bell X-plane 1, and the
American plane X-15
