The Landing Gear

1. The landing gear or undercarriage is the main structural unit of the aeroplane. It serves for supporting and taxying the aeroplane on the ground and it must absorb the energy of landing. The landing gear consists of the main and auxiliary units. Being attached near the centre of gravity of the machine the main landing gear forms the principal support of the aero­plane.

2. The auxiliary landing gear may be either at the tail as a tail wheel, or at the front of the fuselage, as a nose wheel. The landing gear with the nose wheel is called a tricycle landing gear.

3. The main landing gear includes wheels for taxying on the ground, shock-absorbers for absorbing the energy of landing, wheel brakes for slowing up the motion of the aeroplane during taxying, retracting mechanism with controls, indicators and warning devices for retracting the landing gear during the flight and structural members for attachment of the landing gear to the primary structure.

4. An exposed landing gear creates a considerable amount of drag and thus lowers flying speeds. This disadvantage is eliminated by the use of retractable landing gear that is, gear which is retracted into recesses in the wings or the fuselage or into engine nacelles.

5. Retraction may be accomplished by electrical or hydraulic systems or manually. Usually, electrically or hydraulically operated units have manual controls for emergency use.

II. Найдите в тексте ответы на следующие вопросы:

1. What is the function of the landing gear?

2. What does the main landing gear form?

1. The engine is said to have failed due to filter clogging.

2. The design of the engine was reported to have some drawbacks, one of them being insecure attachmeat of turbine buckets.

3. Drag appears to vary directly with the square of the velocity
of the aircraft.

4. The vertical speed of the plane is certain to vary according
to the load the airplane carries.

V. Перепишите и переведите следующие предложения. Обратите внимание на конструкцию "самостоятельный причастный оборот" (см. модель):

1. The motion about the lateral axis is affected by means of elevators, which are actuated through a system of levers and cables, the control stick being situated in the cockpit.

2. Ice having been formed on the screens, they are automatically retracted.

3. The wing flaps are for improved take off and landing, the operations the ailerons giving lateral control.

4. The aircraft windows have double panes: one pane being broken, the other can withstand full pressure.
