TYPES OF LANDING GEAR
The basics of the landing gear was explained in the before posts.(https://sabaeroline.blogspot.com/2020/06/aircraft-landing-gear.html) Landing gear types would clearly explain in the present post. As pilot tries, Not Every Aircraft landing is perfect due to Bad weather conditions, short landing etc., Landing gear play important role at time of rough landing, handles the aircraft smoothly and safely landing without breaking or collapsing the aircraft into pieces.
TYPES OF LANDING GEAR
There are many types of Landing gear. The types of landing gear used in the aircraft depend on two things design of the aircraft (like military, civil purpose) and its intended use (like Cargo, commercial).There are three main types of landing gears used.
Tail wheel Landing Gear
Tail wheel Landing Gear is also known as Conventional or traditional type landing gear because this was milestone for majority of the aviation history, used in the other legendary fighters of WW2. The main gear are located forward to centre of gravity of flight, which makes the tail to get support from the third wheel assembled in the tail of the aircraft. In some aircraft skid replaces the third wheel which helps slow the aircraft while landing and provide direction stability in earlier aircraft.
By raising the angle of fuse large when fitted with conventional gear allows to fix long propeller in front of engine for older aircraft, It also provide increase ground clearance of the forward fuse large with is also a advantage in using Conventional Landing Gear.
Directional stability is controlled by different breaking system until the aircraft speed comes under the control of the Rudder. Steerable tail wheel connected to the rudder and rudder pedals by cables. For smooth and easy landing springs fixed for damping.
Tandem landing gear
Most of the aircraft using tandem landing gear are military planes and spy planes. This type of landing gear has a main gear andtail gear aligned on the longitudinal axis of the aircraft.
The main advantage of Tandem landing gear design reduces drag when deployed they are retractable.
Tricycle-type landing gear
The most common type landing arrangement used in modern aircraft is the Tricycle-type landing gear consist of a nose gear and main gear. Larger and small aircraft today used this gear arrangement.
Benefits
- Allows more forceful application of the breaks without noise created over when Breaking which increases high landing speed.
- Provides better visibility from the flight while landing and ground maneuvering.
- Weights are equally spread over large area and are equally distributer each Gears provide a better safety margin.
- Aircraft centre of gravity lies forward of the main gear, force act on CG point makes the aircraft moving forward avoiding looping which prevents groung-looping.
Landing Gear Design
Depend on the Aircraft usage and operation the landing been designed either Fixed Gear (immovable) Retractable Gear(movable).
