The fighter Aircraft are classified as generations according to their Design, Avionics and weapon system. Thus we have five generations of fighter aircraft and sixth generation fighter aircraft are in testing phase. When we invent something new that can be used in fighter aircraft but cannot be upgraded on the existing aircraft then we design a new Continue reading “Generations of Fighter Aircraft”
Ballistic missiles are the one following a ballistic trajectory or parabolic path. It reaches the target in the consideration of launching angle, launching speed (like javelin throw) and earth rotation. The ballistic missile needs engine power only for the half of the flight Continue reading “Difference between Ballistic and cruise Missiles”
Stealth aircraft have ability to hide from enemies radar. People using Radar, Infra red, RF spectrum, visible light and audio to detect the aircraft or missiles flying in their airfield. The stealth aircraft are designed to avoid detection from the above things using emission Continue reading “Indian Stealth Aircrafts”
BrahMos missile is india’s proud.
BrahMos is one of the world’s fastest cruise missile (Mach 2.8-3), BrahMos II (Mach 7-8).
Cruise missile means it can be driven to the target ,it will fly in the predetermined path. It needs engine power through the whole flight , We can program the path of the missile.
BrahMos missile is the joint project of India and Russia. The name was given by joining the Continue reading “BrahMos Missile”
Ramjet engine is a very simple air breathing engine (requires atmospheric air to work). It has no moving parts, So less weight easy to built even though it can produce super sonic velocity.Working of the ramjet engine based on Ram Effect.
RAM EFFECT AND RAM PRESSURE
The kinetic energy of air converted into pressure ,this effect is known as ram effect, and Continue reading “Ramjet Engine”
When an aircraft flies at subsonic speed (0 M to 0.8 M) the velocity of the air over the wing will be in the subsonic limit.
But an aircraft flies at transonic speed (0.8 M to 1.2 M) the velocity of the air over upper surface of the wing will reach supersonic speed (1.2 m to 5 m).
This supersonic speed will cause shock waves over the upper surface of the wing, the shock wave causes flow separation on the upper surface of the wing , This flow separation Continue reading “Super Critical Airfoil”
