Technical field the utility model relates to a kind of wire controlled push rod model airplane drive unit of being held up or placed ground by operator's hand.

The present model airplane aircraft power of background technology has two kinds substantially: a kind of is internal-combustion piston engine, and another kind is to use battery to make the motor of the energy.Although internal combustion engine horsepower is greatly, because noise is big, start difficulty, and tail gas pollution is serious, handle inconvenience, limited its application greatly; Although motor is handled easily, noiseless is not polluted, and the horsepower that is provided is less, and model of an airplane airborne period is short.More than two kinds of power modes all be that power set are installed on the model of an airplane body, owing to limited by flying weight, can be all very limited for the power that the model airplane aircraft provides, be weight reduction, it is very light that the model airplane aircraft must be made, so just greatly reduce model of an airplane body intensity, if misoperation Crater face is easy to damage, this has limited popularizing of model airplane to a large extent.

The summary of the invention the purpose of this utility model is to overcome weak point in the prior art, and a kind of new-type model airplane drive unit fully is provided, and can provide enough power for the model airplane aircraft, and need not consider the restriction of flying weight.

The purpose of this utility model can solve by following technical scheme: this drive unit is mainly by a push rod, a motor (or internal combustion engine) that has propeller, a motor that has reel, a control box and one or two high-strength filaments compositions.Have the outer end of the motor mounting of propeller at push rod; Control box (inside has circuit for controlling motor and power supply) and have the other end of the motor mounting of reel at push rod, one end of silk thread is wrapped in the wire casing of reel of winding motors, and the guide ring that the other end of silk thread passes the push rod outer end is connected with the model of an airplane.

When flying model aeroplanes, operator's hand is held up the end that push rod has control box, earlier silk thread is adjusted to suitable length by winding motors, start propeller motor (or other engines) then, propeller just can promote push rod and moves in a circle around the operator like this, then drive the model of an airplane by silk thread and do circular flight, can shrink or discharge silk thread, thereby reach the purpose of control model of an airplane flying radius by the control winding motors around the operator.Have the rotating speed of propeller motor by control, flying speed that can the adjustment model aircraft so just can make the model of an airplane fly in a radius variable space.When the length ratio of silk thread and push rod is excessive, according to the circular motion theory, the power of propeller is difficult to pass to the model of an airplane, thereby can make the model of an airplane produce the phenomenon of stall, at this moment can be by shrinking the length of silk thread, the flying radius of the model of an airplane is dwindled, also can give the model of an airplane simultaneously, make the better of model of an airplane flight the transmission of power of coiling electric motor.

In order to make this device not only can the driving model aircraft flight, can also control the flare maneuver of the model of an airplane, can use two rhizoid line trailed model aircrafts, two wire casings will be opened on the reel, two rhizoid lines are wrapped in respectively in two wire casings, two rhizoid lines pass two guide rings that are positioned at the push rod outer end respectively, be connected with the model of an airplane, winding motors is made can be around the structure of its fixed axis rotation, when the operator tilts with the hand-drive coiling electric motor like this, just can make two rhizoid lines produce length difference, thus pulling be installed in model of an airplane body inner rocker arm on have a down dip, rotate up and down with this horizontal rudder plate of controlling the model of an airplane.

This model airplane drive unit also can be made and have only a propeller motor, and the structure of the silk thread of a regular length is fixed on the outer end of push rod with an end of propeller motor and silk thread, and the other end of silk thread is connected with the model of an airplane.The operator drives radius flights such as propeller motor trailed model aircraft work.The motor of band propeller can replace with internal combustion engine.Described silk thread can be nylon wire or steel wire.

The utility model compared with prior art has following advantage: this Power Drive Unit is separated dynamical system and operating mechanism and model of an airplane body, whole power and operating mechanism are held up burden by operator's hand fully, so just alleviate the flying weight of the model of an airplane greatly.Because the model-driven device held up by operator's hand, that drive unit can be done is bigger, and weight also can be greatly, facilitates like this to the model of an airplane enough big power is provided.Because enough big power has been arranged, what the model of an airplane also just can be made is enough firm attractive in appearance, and the ground just in case misoperation is fallen also is not easy to break.Simultaneously also can make the model of an airplane have more internal mechanism, produce more function, strengthen the interest and the easy operability of the model of an airplane greatly, make the universal possibility that becomes of the model of an airplane.Also the drive unit of the whole model of an airplane can be fixed on some places on ground, control the flight of the model of an airplane by the mode of remote control.
