Types of jet engines
All jet engines and gas turbines work in broadly the same way (pulling air through an inlet, compressing it, combusting it with fuel, and allowing the exhaust to expand through…
What is a jet engine?
A jet engine is a machine that converts energy-rich, liquid fuel into a powerful pushing force called thrust. The thrust from one or more engines pushes a plane forward, forcing air past…
How A Turboprop Engine Works
Turboprop engines combine the reliability of jets, with the efficiency of propeller driven aircraft at low to mid altitudes. Found on anything from a 50+ seat passenger aircraft to a single…
Turboprop Engine
To move an airplane through the air, thrust is generated with some kind of propulsion system. Many low speed transport aircraft and small commuter aircraft use turboprop propulsion. On this page we will discuss some of…
What is Mach Number?
The Mach number is the ratio of flow velocity after a certain limit of the sounds speed. In simple words it is the the ratio of the speed of a…
Aerofoil
Definition of aerofoil Aerofoil or airfoil is defined as the cross-sectional shape that is designed with curved surface giving it the most favorable ratio between lift and drag in flight.…
Aerodynamic Lift, Drag and Moment Coefficients
In the previous post we introduced the four fundamental forces acting on an aircraft during flight: Lift, Drag, Thrust and Weight and examined how they interact with one-another. We are now going…
What is Lift?
Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on…
Newton’s Laws and Flight
Law 1: Inertia The law of inertia has two parts. The first part states that an object at rest will stay at rest unless acted on by a force. A force…
