ROTORCRAFT SKID AND ROTORCRAFT WITH SAID SKID Russian patent published in 2010 - IPC B64C25/52 

FIELD: transport.

SUBSTANCE: invention relates to skid rotorcraft. Proposed rotorcraft comprises airframe and skid with skids interconnected by first and second crosswise elements, first and second jointing elements designed to joint first crosswise element with airframe and one central third jointing element arranged to transmit force from second crosswise element to airframe and vice versa. First jointing elements comprise two first parts to be arranged on first crosswise element to rest thereon. First jointing elements transmit forces from first crosswise element to airframe. Second jointing elements comprises two second parts to be arranged on first crosswise elements to rest thereon and to pass outside first parts on both sides. They become active only when deformation of the first crosswise element reaches or exceeds preset strain in rolling or vertical slipping.

EFFECT: simplified design, reduced load on passengers in landing.
