Title: Helicopter
Inventor: SUGIYAMA KATSUMASA
IPC: B64C21/00
Filed: 1990-07-06
Abstract: PURPOSE:To reduce vibration and improve descending performance in a helicopter, provided with a body formed into approximately rectangular cross section from the view in the flying direction, by providing rectifying means for preventing air flow breakaway around the periphery of the body at the descending time of the helicopter, at the upper part and lower part of the body. CONSTITUTION:In a helicopter 1, its body 3 formed into approximately rectangular cross section is comparatively angular. Accordingly, when air flow hits the body 3 at the time of descending, the air flow is apt to break away at the part with large curvature of the body cross section, that is, on both right and left sides of the helicopter lower part and on both right and left sides of the helicopter upper part. Flaps 11 are therefore provided on the right and left sides of the body lower part and on the right and left sides of the body upper part by flap fixtures 13. Vertical flow around the body 3 is thereby placed in the non-breakaway state 12, so that the vibration and noise of the helicopter 1 is reduced, and also the descending performance of the helicopter is improved.
