FIELD: instrument making.SUBSTANCE: invention may be used in military equipment when designing rockets with optical self-homing heads (OSHH). The optic-electronic tracking coordinator comprises a biaxial gimbal joint with angle sensors and stabilisation motors, a sensitive element - a three-degree gyroscope with angle and torque sensors fixed with the possibility of its rotor rotation around the axis X, perpendicular to axes Y and Z, a unit of command generation to an actuating device, and also a laser range finder comprising a transmitting and a receiving units.EFFECT: invention makes it possible to expand functional capabilities of a coordinator being a composite part of a gyrostabilised OSHH, in respect to accuracy of automatic signal generation for operation of an actuating device with account of approaching speed, and also a target type.1 dwg

Optic-electronic tracking coordinator

An aircraft landing gear includes at least one load bearing longitudinal structural element. The longitudinal structural element is hollow and is arranged to have a non-structural element located inside.

Aircraft landing gear

FIELD: aircraft engineering.SUBSTANCE: device comprises first shaft 10 fitted at aircraft to run about axis R, second telescopic shaft 20 mounted at undercarriage to run thereon and to extend along undercarriage almost to the wheels, means 19 to transmit rotation from said first shaft to said second shaft, means 21 to transmit rotation from second shaft to one wheel. Besides, proposed device comprises means 30 for selective braking of one of said shafts relative to undercarriage and first shaft drives 11, 15. In undercarriage lift, undercarriage rigid retaining tool is unlocked. Then, shafts are locked relative to undercarriage by actuating wheel brake or aforesaid selective braking means. Then, drives are actuated to make first shaft run. Then, shafts are locked relative to undercarriage by actuating wheel brake or aforesaid selective braking means. Then, forced running of engine caused by lowering of undercarriage is controlled for adjustment undercarriage lowering.EFFECT: combined functions of lifting-lowering, wheel drive, aircraft ground run drive, extra means for braking and power takeoff in braking.3 cl, 7 dwg
