Description
Technical field
Unmanned plane air speed technical field is the utility model is related to, is applied to unmanned plane differential type air speed more particularly to one kind
The pitot of sensor.
Background technology
In existing technology, measurement unmanned plane is mainly also to rely on sky in flight course relative to the speed of air
Speed pipe and airspeed sensor, air speed be unmanned plane produce lift necessary condition, air speed is inadequate, aircraft will stall, especially
Be fixed-wing unmanned plane during autonomous flight, the detection that autopilot need to pass through to air speed adjusts the power of aircraft flight.
Conventional air speed detection means separates dynamic air inlet and static air inlet, not in one, relative gas that airspeed sensor is obtained
Stream error is big, and separated detection means is inconvenient to be installed on unmanned plane, and influenceing relative wind attractive in appearance, inaccurate causes to fly
Machine flies control and calculates the air speed to make mistake, causes to influence the subsequently a series of operation of aircraft, reduces the service life of unmanned plane, because
This, it is desirable to provide a kind of pitot suitable for unmanned plane differential type airspeed sensor, counted for improving unmanned plane in flight
The accuracy rate of the flight airspeed of calculation.
Utility model content
The purpose of this utility model is that to solve the above problems and provided a kind of empty suitable for unmanned plane differential type
The pitot of fast sensor.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of pitot suitable for unmanned plane differential type airspeed sensor, including fixed seat, metal airway, it is described solid
3 fastened by screw holes are provided with reservation, the fastened by screw hole is provided with fixed plate, is provided with inside the fixed seat below
Tracheae groove, the tracheae groove are used to lay tracheae, dynamic air admission hole are provided with the metal airway, under institute's dynamic air admission hole
Side is provided with 2 static air admission holes, and the metal airway bottom is provided with dynamic air current connecting tube, the dynamic air current connection
Static air-flow connecting tube is provided with beside pipe.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, the metal is led
Tracheae top is provided with the dynamic air admission hole, and the dynamic air admission hole passes through internal structure phase with the dynamic air current connecting tube
It is logical.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, the dynamic is entered
There are 2 described static air admission holes below stomata, the static air admission hole passes through internal structure with the static air-flow connecting tube
Communicate.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, the fixed seat
Set orthogonal, ensure that the metal airway is parallel with the fixed plate after fixation.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, the dynamic gas
After stream connecting tube connects tracheae with the static air-flow connecting tube, passed through the tracheae groove, facilitate attractive in appearance, facilitate tracheae another
Head connection differential type airspeed sensor.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, 3 spiral shells
The metal airway and the fixed seat, are linked to be an entirety by silk fastener hole fastened by screw.
In order to avoid the inaccurate influence of differential type airspeed sensor relative air speed during unmanned plane during flying, the fixed plate
Pasted through glue, the pitot is pasted onto on unmanned plane, direction is aircraft direction of advance, and the metal airway faces
Direction of advance air inlet.
The beneficial effects of the utility model are：Whole pitot is easy for installation, will be flown by the metal airway
During relative wind be incorporated on differential type airspeed sensor, accurately calculate unmanned body flight course flight speed
Degree, is fastened by the fastened by screw hole, is pasted onto by the fixed plate on unmanned aerial vehicle body, simple to operate, practical.
