Description
Technical field
The utility model belongs to technical field of aircraft structure design, in particular to a kind of pre-buried discharge brush of wing tip
Structure.
Background technique
Aircraft or aircraft can encounter various atrocious weather situations in flight course, wherein threaten it is biggish be exactly
In thunderstorm weather, aircraft, which has, larger can suffer from being struck by lightning.Lightning stroke is aircraft when by being struck by lightning to the main harm of aircraft, high pressure
The insulating materials and partial structurtes of aircraft surfaces can be punctured, high current can make conduction on airframe discontinuously locate on fire or cause
Material corrosion causes the mechanical performance of aircraft to decline to a great extent, or even causes danger, therefore the lightning protection design of aircraft is aircraft
Indispensable component part in structural system design.For aircraft when meeting with lightning stroke, the body of aircraft is as lightning discharge access
In a component part, the inlet point an of lightning stroke and leaving a little for lightning stroke are certainly existed on the body of aircraft.Lightning stroke
To leave a little be exactly point of discharge of the aircraft to atmosphere, point of discharge is usually located at the tail portion of aircraft, it is most likely that horizontal tail, vertical fin,
On the rear of rudder or at the tail point of fuselage.Therefore, the anti-lightning strike electric discharge measure of usual aircraft be wing, horizontal tail, vertical fin,
The appropriate location installation of the wing tip rear of rudder puts a brush and carries out conductive discharge, the injury for avoiding aircraft from being struck by lightning.But
Traditional discharge brush is installed by the discharge brush support being installed on the wing tip rear of wing, horizontal tail, vertical fin, rudder
Connection, and in order to guarantee stability of the discharge brush in aircraft flight, it is also necessary to by one or more fasteners to electric discharge
It is fastened between brush support and wing tip, discharge brush and discharge brush support.This mode has resulted in assembly when installation discharge brush
It is cumbersome, while the heavier-weight of discharge brush and discharge brush support, aerodynamic drag is also increased, gas when aircraft flight is brought
Dynamic loss.Especially in unmanned plane field, traditional electric discharge brush configuration is difficult to meet the high speed of unmanned plane, high stealth is wanted
It asks.Therefore for defect existing for conventional discharge brush configuration, the utility model discloses a kind of pre-buried electric discharge brush configurations of wing tip.
