Abstract
The invention discloses a kind of cross flow fan lift-rising autogyros, include fuselage, rotor, propeller, undercarriage, empennage, engine, the first cross flow fan, the second cross flow fan, first motor and the second motor；In afterbody, the shaft of output shaft and the propeller is connected for engine setting；Rotor is when gyroplane advances by incoming flow rotation to provide lift；First cross flow fan, the second cross flow fan are arranged in fuselage two sides；First motor, the output shaft of the second motor are connected with the shaft of first cross flow fan, the second cross flow fan respectively.The present invention utilizes the cross flow fan of two sides, and upward lift is generated while increasing gyroplane thrust, realizes autogyro very short takeoff and landing.The present invention can very short takeoff and landing, High Angle of Attack not stall, manipulation and control is simple, low-speed operations stability is good, high security reliability.
Description
Technical field
The present invention relates to aviation fields, and in particular to a kind of cross flow fan lift-rising autogyro.
Background technique
In recent years, with the fast development of various aircraft, autogyro is because its structure is simple, manufacturing cost is low, peace
The advantages that Quan Xinggao, in the industry cycle gets the attention, and has a extensive future.Most of autogyros cannot as helicopter into
Row VTOL, and must can just take off as fixed wing aircraft by sliding race.However as the development of science and technology, for rotation
The performance of gyroplane and security requirement are continuously improved, and increasingly pursue a take off apart from shorter, safety is higher, handling
Better autogyro.
Cross flow fan is a kind of device of novel generation aerodynamic lift, it generates whirlpool liter using the preposition rotary fan of aerofoil profile
Power and thrust are flown, and have many advantages, such as that low-speed performance is good, load is big and High Angle of Attack not stall, by domestic and international associated mechanisms
With the concern of researcher.The fan wing generates lift and consists of two parts: a part is the wing latter half when fan rotation
The flow velocity of upper and lower surface is different, causes the pressure difference of wing upper and lower surface, forms the lift of wing；Another part is because of fan
When rotation, a very strong eccentric whirlpool is generated inside fan, stronger eccentric whirlpool low-pressure area is caused, so that wing first half
The upper and lower surface in partial arc shape region generates biggish pressure difference, forms larger portion of airfoil lift, i.e. vortex lift.At present
The cross flow fan wing has been applied on aircraft, but mainly uses on fixed wing aircraft, and answering on autogyro
With not yet.
Based on this, a kind of autogyro equipped with cross flow fan is proposed, realize greater lift, shorter distance of taking off,
Greater security, more preferable maneuverability.
Summary of the invention
To be solved by this invention is that current autogyro takes off the small disadvantage of lift, provides a kind of cross flow fan and increases
Rise autogyro.Specifically, a kind of cross flow fan lift-rising autogyro is equipped with cross flow fan in fuselage two sides, increase rotation
Upward lift is generated while wing machine thrust, realizes autogyro ultra-short takeoff.
The present invention uses following technical scheme in order to solve the above problem:
A kind of cross flow fan lift-rising autogyro includes fuselage, rotor, propeller, undercarriage, empennage, engine, the first cross
Flow fan, the second cross flow fan, first motor and the second motor；
Engine setting is in afterbody, and the shaft of output shaft and the propeller is connected, for driving propeller to turn
It moves to provide forward thrust；
The empennage is arranged in afterbody, for yawing；
The rotor setting is in fuselage roof, by incoming flow rotation to provide lift when gyroplane advances；
The undercarriage is arranged in fuselage bottom, rises and falls for gyroplane；
First cross flow fan, the second cross flow fan are arranged in fuselage two sides；The first motor, the second motor are arranged at
In fuselage, output shaft is connected with the shaft of first cross flow fan, the second cross flow fan respectively；
First cross flow fan, the second cross flow fan are for generating lift while providing thrust.
When taking off, propeller is worked at the same time with cross flow fan, and propeller provides autogyro thrust, and cross flow fan exists
Lift is generated while thrust is provided, and realizes autogyro very short takeoff and landing.State of flight in the sky, cross flow fan can pass through
Increase and decrease the lifting of the revolving speed control autogyro of cross flow fan, the other side can be increased by reducing side cross flow fan revolving speed
Cross flow fan revolving speed controls autogyro posture.
The invention adopts the above technical scheme compared with prior art, has following technical effect that
Autogyro of the present invention take off apart from shorter, High Angle of Attack not stall, manipulation and control is simple, low-speed operations stability is good,
Safety high reliablity.
