Description
Technical field
Take a flight test guarantee apparatus field the invention belongs to depopulated helicopter, be related to test when taking a flight test using arriving
A kind of special protection device of taking a flight test of wheel undercarriage depopulated helicopter.
Background technology
Depopulated helicopter is different with unmanned fixed wing aircraft, and due to there is rotor, its aerodynamic characteristic and dynamics are special
Property it is complicated far beyond fixed wing aircraft, be that item is multidisciplinary, mutli-system integration modernization high-tech project, therefore
Technically difficulty is very big.Depopulated helicopter is balance, compensation, decoupling of pilot guidance helicopter etc.
Technology, reflects in flight control system exactly, thus the research of depopulated helicopter plant characteristic is more than having
The requirement of people's helicopter is high, is also to carry out the technical scheme that over the horizon autonomous flight must be studied and solved.
Because depopulated helicopter is operated without pilot on body, and new body is unstable also unreliable, flies control
System imperfection, on trickle Parameters variation, flight control system can not pass through fuzzy operation as pilot
Carry out the pose adjustment of body, it is necessary to first be tethered at taking a flight test.It is tethered at that to take a flight test be to check depopulated helicopter
Each system working condition of full machine, and the ability to work and state of each system are tentatively examined, particularly fly control system
The function and state of system, make full machine reach the state of the art that can be taken a flight test with near-earth hovering.And be tethered at and take a flight test therewith
Near-earth hovering afterwards, is protection body, increases the scope of contacting to earth of body undercarriage, it is necessary to using to the guarantor that takes a flight test
Protection unit, so as to can to a certain extent reduce the rollover of body and preceding turn over that (body carries shoe, can prevent
Turned over after body).
The protection device of taking a flight test of existing depopulated helicopter is all only applicable to the body of skid landing gear, such as V750
With honeybee depopulated helicopter.The protection device of V750 has reached increase body undercarriage and has contacted to earth the purpose of scope,
But it is completely independent between protection device, it is impossible to the impact for bearing to rise and fall when colliding with, is not had under case of emergency
Protect the effect of body.Honeybee depopulated helicopter is coaxial dual-propeller, itself flight attitude stabilization, protection
All around span is not enough for device, and the protective effect played under case of emergency is not enough.Industry helicopter institute of Air China
Skid landing gear depopulated helicopter take a flight test protection device use for reference honeybee depopulated helicopter take a flight test protection dress
Put, and carry out the extension of span, successfully protect nobody to go straight up to when hovering with entering and taking a flight test being tethered to take a flight test
Machine.
The content of the invention
Wheeled depopulated helicopter protection device of taking a flight test uses for reference Air China's industry helicopter all of skid landing gear
The principle of protection device of taking a flight test, the actual installation according to wheel undercarriage depopulated helicopter needs to redesign examination
Fly the structure type and mounting means of protection device erection joint, make full use of the structure of body to be fixed examination
Fly protection device.
Including depopulated helicopter body, cross-protection frame, symmetrically arranged preceding anchor tip outer member, symmetrically
The preceding anchor tip medial side part for setting, covers, symmetrically arranged vertical protection on symmetrically arranged preceding anchor tip
Frame, rear anchor tip left member, rear anchor tip right member is covered on rear anchor tip；Preceding anchor tip outer member
The left and right both sides in front of depopulated helicopter body are individually fixed in using bolt with preceding anchor tip medial side part
On wheel undercarriage；After rear anchor tip left member and rear anchor tip right member are fixed on into depopulated helicopter body
On the wheel undercarriage of side；Cross-protection frame is positioned over preceding anchor tip outer member cross-protection frame mounting groove
It is interior, vertical protection frame is positioned in the vertical protection frame mounting groove of anchor tip left member and anchor tip right member,
And set respective spacing；By being covered on preceding anchor tip preceding anchor tip outer member is individually fixed in using bolt
With preceding anchor tip medial side part；Will on rear anchor tip lid make to be bolted to rear anchor tip left member and after
In anchor tip right member.
Taken a flight test protection device using the wheeled depopulated helicopter, be tethered at that take a flight test can be maximum when being taken a flight test with near-earth hovering
The safety of limit ground protection depopulated helicopter body, increase undercarriage contacts to earth scope, reduce the rollover of body with
Before the angle turned over.
