Aircraft carriers are divided into two main types:
USA, France, Brazil: CATOBAR
(Catapult Assisted Take-Off But Arrested Recovery or Catapult Assisted Take-Off Barrier Arrested Recovery)
In other words: During takeoff of the aircraft uses its own engines and is supported by a catapult. Front landing gear have a special mount. There is a special system which connects to the front gear of aircraft and supports the airplane during takeoff. Aircraft during take-off is literally pulled & nbsp; by the rail. The landing takes place by retracting a special hook in the back of the plane to catch the rope on the carrier. There are 4 lines. The best to catch 3rd rope counting from the back of the ship.
Russia, India, China: STOBAR
(Short Take-Off But Arrested Recovery)
In other words, the plane takes off only using it’s own engines (no catapults) and a special curved hill in the forward part of the aircraft carrier. & Nbsp; The landing takes place by retracting a special hook in the back of the plane to catch the rope on the carrier.
Advantages of STOBAR compared to CATOBAR: generally simpler and cheaper design, construction and operation
Disadvantages of STOBAR compared to CATOBAR: require aircraft with a big & nbsp; power to mass ratio, so limit the types of supported machines
How do you land on an aircraft carrier?
The aircraft is equipped with a hook. Yes, the hook. Before landing, the hook slides out on the boom & nbsp; from the back of the plane. & Nbsp; For more explanation I quote from Wiki, because there is no point in me saying something that someone else has pretty well explained:
“The arresting gear consists of several thick steel cables, usually four, mounted across the deck of the boot to the special cartridge system. These lines are installed at a height of more than a dozen, and sometimes even more than 20 cm above the surface of the landing. The purpose of the pilot landed the aircraft is to catch the a special pop-up part of the tail hook for one of the ropes, causing rapid deceleration of the machine section from a dozen to several dozen meters. Ropes arresting gear on the carrier are numbered from 1 to 4 from the stern, a perfect landing is to catch the rope number 3. Strength suppression ropes inhibit is adjusted depending on the type of landing the plane and its mass, so before landing, the pilot reports use the deck startup condition of the fuel and weapons. too loose rope can stop the aircraft before the end of the deck, while too much tension can seriously damage the machine. Overload during landing by means of arresting gear comes to 4 g.
During landing on an aircraft carrier, there is a risk that the plane did not catch any of the cables braking because of safety reasons, approach the machine to the landing takes place at over engines of about 85% of the maximum, until you touch the deck of the wheels of the main landing gear, the pilot increases power to 100%. When the plane is stopped pilot reduces power to a minimum, and then increases the hook rope releasing the arresting gear. Such a method provides an appropriate landing speed and provides you pick up a construction where the hook does not interfere with any of the lines. ”
Hope one day I will film on the aircraft carrier.
