Description

A kind of radome fairing for placing lock
Technical field
The utility model is related to helicopter structure design fields, and in particular to a kind of radome fairing for placing lock.
Background technology
The radome fairing of aircraft is for adjusting air-flow, and in order to reduce in the skyborne resistance of aircraft, radome fairing is as possible with streamline Type designs, and enables air-flow is smooth to pass through.
When Helicopter Dome is opened, system maintenance channel can be used as;When closing, built-in system and equipment are protected, and subtract Aerodynamic drag in few flight course, radome fairing generally use hinge or locking mechanism are connect with housing construction, therefore radome fairing It is movable part.The locking mechanism of existing helicopter fuselage bottom rectifying cover uses hanging-ring type locking mechanism, lock point installation Tapered platform, heavier-weight are enriched in face using filler, and its lock point opening need to break rectification shroud rim, affect radome fairing Edge integrity, rigidity and mechanical property are poor.In contrast, the lock point mounting surface lighter in weight of existing design, rigidity is preferable, Remain the integrality of rectification shroud rim, specious smoothness.
Utility model content
The utility model designs a kind of radome fairing for placing lock, under the premise of meeting radome fairing basic function, increases by 6 Place the mounting surface of hook lock in place.It is designed by profile optimization, according to a lock point position at 6, in the bottom rectifying cover of smooth surface Invagination installation lock platform at upper design 6, the platform are that curved surface smoothly transits to invagination plane, are used in combination the double-deck carbon cloth to around it Reinforced.
The utility model places the radome fairing of lock, including rectification cover body, and the lock being arranged on rectification cover body Seat mounting groove, the rectification cover body includes glass cloth prepreg, and the paper honeycomb coated by the glass cloth prepreg, institute It includes glass cloth prepreg and the carbon cloth prepreg that is coated by the glass cloth prepreg to state lock mounting groove, the lock peace Through-hole is provided on tankage, for installing hook lock.
Preferably, at least two layers of the carbon cloth prepreg.
In said program preferably, the carbon cloth prepreg is layer 2-4.
In said program preferably, the thickness of the lock mounting groove is generally the thickness of radome fairing having at cell The 1/6-1/5 of degree.
In said program preferably, the glass cloth prepreg is at least 8 layers.
In said program preferably, the lock mounting groove on the radome fairing for placing lock is towards internal body Groove depth is more than it in the groove depth towards engine body exterior.
Key point of the present invention:Installation requirement is locked according to hook, invagination lock platform at 6 is designed on the radome fairing of curved surface, And lock point cooperation position is locked according to hook, trepanning is carried out in mounting platform, realizes that hook locks locking functions.
Lock mounting surface is plane:Due to locking locking mechanism using hook-type, work(is installed and used for guarantee hook-type lock button Can, it is more difficult that lock mounting surface is directly designed on the curved surface of bottom rectifying cover.Therefore, surface blending is used on radome fairing Lock mounting surface is designed as plane by the design method for plane of invaginating, and the lock of connection hook-type lock then directly falls within lock installation On face.
The advantages of the utility model is:
1) installation of the hook-type lock lock in the curved surface radome fairing of greater curvature is realized;
2) plane of mounting platform be by original by curved surface influenced everywhere in a lock point lock be designed as that same part is suitble to lock Seat provides precondition;
3) the rectification cover outer surface (surface blending to the platform that invaginates) in lock point region is smooth complete, beautiful smooth.
The rigidity of lock mounting surface is reinforced.
The radome fairing that lock can be placed has following advantages:
1. simple in structure:Structure remains using and installing for former radome fairing without reinforcing body rigid structure Function;
2. weight is light:Entire bottom rectifying cover is glass cloth+paper honeycomb structure, and weight is relatively light.Corresponding lock peace Dress face, carbon cloth reinforce the weight very little generated;
3. easy for installation:Lock is rest directly upon on radome fairing, cooperation hook lock quick-release installation.
In contrast, the lock point mounting surface lighter in weight of existing design, rigidity is preferable, remains the complete of rectification shroud rim Property, specious smoothness
