SPRING FOR MAIN LANDING GEAR LIGHT Russian patent published in 2016 - IPC B64C25/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly spring main landing gear light. Spring is made from polymer composite materials and consists of two rigidly interconnected shells. Spring is made hollow. Each of shells is made of thick-wall with variable angle kit orthotropic layer thickness of casing, realised by alternating symmetric building alternating layers of polymer composite materials so that major axis of orthotropy with maximum normal modulus of elasticity layer forms an angle with longitudinal direction of spring with for inner layers of minimum value and monotonously increasing as they approach to external surface so that when bent spring all its layers are equally strong.

EFFECT: reduced drag in flight at minimum possible weight, sufficient stiffness in bending and torsion, efficient damping.
