Is a Brayton cycle general form of engine producing a shaft work output in the process, used to drive the compressor.

Gasturbine Engine

is a type of engine that uses complex mechanical systems like cranks shaft, camshaft, piston, connecting rod, rocker arm and valves to produce power that drives the propeller.

Powerplant 1

is a type of engine that uses complex mechanical parts in order to drive a jet, fan, propeller, shaft or rocket

Powerplant 2

first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1687

Sir Isaac Newton

Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in?

1687

states that for every action, there is an equal and opposite reaction. Jet propulsion applies this law by taking in a quantity of air and accelerating it through an orifice or nozzle. The acceleration of the air is the action and forward movement is the reaction.

Newton’s 3rd Law

as the velocity increases, pressure decreases.

Bernoulli’s Principle

Is related in nature that propels itself through the water using a form of jet propulsion.

Squid

The person we referred to as the god father of jet propulsion which contributes a huge ideas related to Gasturbine engines

Hero Alexandria

Year that a writer and mathematician named Hero devised a toy that used the reaction principle.

250 BC

Is considered to be the first recorded steam engine or reaction steam turbine. is a simple, bladeless radial steam turbine which spins when the central water container is heated.

Aeolipile

Built the Chimery jack painting which gave idea about using exhaust gases into a working machine

Leonardo Da Vinci

Year that a was an Italian polymath of the High Renaissance who is widely considered one of the greatest painters of all time produce the painting of Chimery jack.

1500

The one who had the opportunity to apply some of his concepts in the development of the turbo-supercharger. This unique supercharger consisted of a small turbine wheel that was driven by exhaust gases. The turbine was then used to drive a supercharger.

Dr. Sanford Moss

lower that mach 1

Subsonic

equivalent to mach 1

Transonic

higher than mach 1 upto mach 5

Supersonic

mach 5 above

Hyper sonic

Air breathing jet engine that uses the engine's forward motion (Mach 3 - Mach 6) to compress incoming air without any axial compressor or a centrifugal compressor.

Ramjet

Air breathing jet engine that uses the engine's forward motion (Mach 6 above) to compress incoming air without any axial compressor or a centrifugal compressor.

Scramjet

Is a type of jet propulsion non air breathing engine that carries its own fuel (it may be solid or liquid form) as well as the oxygen (it may be solid or liquid form) needed for the fuel to burn.

Rocket

Types of Jet propulsion:

Gasturbine Engine and Rocket

Types of rocket:

Solid propelled and Liquid propelled

Is a type of assisted take-off by using catapult system

CATO

Is a type of assisted take-off by using auxiliary rocket

RATO

Is a type of assisted take-off by using auxiliary jet that can reach at the speed of mach 3

JATO

stored liquid fuel and stored liquid oxidizer are pumped into a combustion chamber where they are mixed and burned.

Liquid Propelled Rocket

is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer)

Solid Propelled Rocket

2 TYPES OF FLAME HOLDER

Solid and Hollow

invented the first British jet, which is the gloster e.28/39

Sir Frank Whittle

made the first turbo jet engine to power an aircraft

Hans Von Ohain

The first turbojet-powered aircraft

Heinkel He 178

is a type of jet propulsion in which the explosion and the resulting hot gas expulsion out the rear of the engine leaves behind an area of low pressure relative to the outside environment within the combustion chamber. •type of engine that can produce thrust and travel at subsonic speed without any moving parts and take off assistance

Pulse Jet

is an effect the momentum of the exhaust gas leaving the cylinder of an internal combustion engine creates a pressure-drop in the cylinder which assists the flow of a fresh charge of air, or fuel-air mixture, into the cylinder. The effect can be maximized by careful design of the inlet and exhaust passages.

Kadenacy Effect

type of engine in which a turbine-driven compressor draws in and compresses air, forcing it into a combustion chamber into which fuel is injected.

Turbojet

engine is a variant of a jet engine that has been optimised to drive a propeller.

Turboprop

sometimes referred to as a fanjet or bypass engine.

Turbofan

engine is a variant of a jet engine that has been optimised to drive a shaft.

Turboshaft

the ramjet provides a simple and efficient means of propulsion for aircraft at relatively high supersonic flight speeds.

Turboram jet

type of spool engine in which all rotating components in the compressor and the gas generator are on one shaft and rotate at the same speed.

Single Spool

type of spool engine that has two concentric shafts that rotate at different speeds: one connects the high-pressure turbine stages to the high-pressure compressor, and the other connects the low-pressure turbine stages to the low-pressure compressor and fan.

Dual Spool

type of spool engine with three concentric shafts, the third of which connects an intermediate pressure turbine and compressor.

Triple Spool

type of blade that can be installed both on compressor or turbine that is connected to the central shaft and rotates at high speed.

Rotor Blades

type of blade that can be installed both on compressor or turbine that is connected to the shroud or casing, is fix and does not rotate.

Stator

a component comprising both rotor disk and blades.

Blisk

thrust produced by the fan to the thrust produced by the engine core exhaust

Thrust Ratio

refers to the ratio of incoming air that bypasses the core to the amount of air that passes through the engine core.

By-Pass Ratio

which is the ratio of air pressure leaving the fan to the air pressure entering the fan.

Fan Pressure Ratio

type of by-pass Engines with more jet thrust relative to fan thrust are known as

Low By-Pass Engines

Type of by-pass engines that commonly has 2:1 to 3:1 ratio

type of by-pass engines that commonly has 4:1 or greater ratio

High By-Pass Engines

measures the temperature of exhaust gasses to identify if combustion chamber is operating at normal range of temperature.

Exhaust Gas Temperature

is the ratio of the turbine discharge pressure divided by the compressor inlet pressure.

Engine Pressure Ratio

is the ratio of the air total pressure (pt) exiting the compressor to the air pressure entering the compressor.
