Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The invention relates to a front fairing of a helicopter power cabin, which comprises a lubricating oil radiator fairing assembly 1 and an oil radiator inlet passage assembly 2 .

[0018] The lubricating oil radiator fairing assembly 1 is formed by bonding the movable oil radiator fairing 3, the left / right hydraulic observation window 4, and the left / right sealing rubber pad 5; the lubricating oil radiator fairing assembly 1 is connected with the cockpit ceiling and The lubricating oil radiator intake channel assembly 2 is connected with angled material screws, and different diameters are used according to the lengths of the two specifications of the screws, so as to prevent errors in fairing reassembly during maintenance. The active fairing 3 of the lubricating oil radiator is a honeycomb sandwich structure of composite material, whi...

Abstract

The invention belongs to a helicopter structure design technology and relates to a helicopter power cabin front fairing. The helicopter power cabin front fairing includes an oil radiator cowl assemblyand an oil radiator inlet port assembly. A lubricate oil radiator fairing assembly is locate at that upper part of the fuselage cabin ceiling and the front part of the final drive fairing; The oil radiator fairing assembly is made of oil radiator movable fairing, left / right hydraulic viewing window and left / right sealing rubber gasket bonded together. A lubricate oil radiator inlet port assemblyis located at that low part of the lubricating oil radiator cowl assembly and the front part of the final drive cowl; As that structure of the invention is light in weight and high in efficiency, beside meeting the basic requirement of the rectifying dimension and the protective equipment, the invention has the functions of a lubricating oil radiating air duct and a cockpit ventilation air inlet,and has good installation and maintenance function.

Description

technical field [0001] The invention belongs to the helicopter structure design technology, and relates to a front fairing of a helicopter power cabin. Background technique [0002] The fairing of the helicopter power cabin mainly plays the role of rectifying the shape, reducing air resistance, and protecting the equipment in the cabin from the influence of the external environment. With the improvement of the comfort level of the helicopter cockpit and the increase of airborne equipment, the fairing of the power cabin meets the basic functions and at the same time puts forward new requirements: the front fairing of the power cabin not only meets the rectification shape, protection equipment, etc. In addition to the basic functions, it should also have the functions of lubricating oil cooling duct and cockpit ventilation air inlet, the function of foreign matter isolation and intake bypass of the air inlet, the function of providing passage and installation holes for the com...
