What is the spike on the front of a jet?

The spike, made of composite materials, creates three small shock waves that travel parallel to each other all the way to the ground, producing less noise than typical shock waves that build up at the front of supersonic jets.

What are the rods on jets for?

These rods are the metal wires you often see sticking out from the trailing edge of airplane wings. An EDR is designed to deal with the friction created during flight, caused by particles such as dust and ice crystal clouds interacting with the airplane’s metal structure.

Why the nose of fighter plane is sharpened?

The pointed nose reduces the strength of the shock wave and therefore the aerodynamic drag force experienced when the fighter aircraft flies at supersonic speeds. Most civil aircraft fly at high subsonic speeds and a rounded nose is the optimum profile for minimum drag at these speeds.

Why does the MIG 21 have a cone?

The inlet cone is shaped so that the shock wave that forms on its apex is directed to the lip of the intake; this allows the intake to operate properly in supersonic flight.

Why do Jets have a pointed nose?

To minimize resistance associated with this shock, hypersonic-speed airplanes are given a pointed nose. The pointed nose allows for a weaker shock so that it doesn’t cause an excessive amount of resistance. Airplanes are given a pointed nose, on the other hand, if they fly faster than the speed of sound.

Why do jets have pointed nose?

Pointed-Nose Airplanes If an airplane flies faster than the speed of sound, it’s given a rounded nose. To minimize resistance associated with this shock, hypersonic-speed airplanes are given a pointed nose. The pointed nose allows for a weaker shock so that it doesn’t cause an excessive amount of resistance.

Why does Concorde have a visor?

To give a smooth line to the nose and to protect the windscreen from kinetic heating during cruise, the first Concorde nose design featured a metal, two-piece visor which would be raised in front of a normal type of windscreen. For take-off and landing the visor would be lowered.
