Abstract
Can deicing air-flow angle sensor the present invention relates to one kind.Weathercock uses internal sandwich package polyimide heater film heating, and, surface polishing, to reach anti-, deicing effect. after weathercock slightly.Using built-in balancing weight, while realize counterweight and spacing.Sealing ring waterproof is replaced using waterproof construction is blocked, prevents rainwater from entering while reduces weathercock staring torque, so as to reduce low speed measurement error.Weathercock corner is measured using Hall angular transducer, is easy to debugging to demarcate.Compact overall structure, it is small volume, in light weight.
Description
Technical field
The present invention relates to one kind can deicing air-flow angle sensor, can be realized by different installation directions and aircraft is attacked
Angle or the detection of yaw angle.
Background technology
Air-flow angle sensor can be used as Aircraft Angle of Attack sensor or sideslip angle transducer to use by installation direction difference.
At this stage can deicing air-flow angle sensor usually using potentiometer or rotary transformer as angular displacement sensor.
But the potentiometer limited precision of absolute linearity, assembling zero-bit regulation are difficult；And rotary transformer volume weight is larger.
At this stage can deicing air-flow angle sensor heating deicing generally use weathercock built-in ceramic heating plate or welding armour
Dress heating cable, both modes all make weathercock thickness thicker, cause balance weight to increase, integral product quality, volume increase,
Usual weight is in more than 300g.
At this stage can deicing air-flow angle sensor generally use rotating shaft sealing circle waterproof, this cause weathercock rotating torque increase
Greatly, weathercock follow-up characteristic is reduced, and then causes using measurement error to increase in low speed flow.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of assembling and setting is convenient, small in volume can deicing
Air-flow angle sensor.
To achieve the above object, the present invention takes following technical scheme：
Using Hall angular displacement chip as angular displacement sensor, small volume is in light weight, and precision is high.Make structure design tight
Gather, reduce product cumulative volume, quality.Measurement range, zero-bit debugging is convenient, reduces Product Assembly, debugging difficulty.
Deicing is heated using the polyimide heater film that only 0.2mm thickness is encapsulated in weathercock, weathercock thickness can be reduced to 2mm
Hereinafter, reduce weathercock weight, counterweight is accordingly reduced, and does not include cable weight only about 85g.
Weathercock omits after using, surface polishing design, makes its ice not easy to hang, further improves anti-icing, deicing capability.
Rotating shaft waterproof blocks design using structure, can reliably prevent rainwater from entering product under condition of raining.It is simultaneously this
Design does not increase axis of rotation torque, will not reduce the measurement error in weathercock follow-up characteristic reduction low speed flow.
