Disclosure of PM:

The technical task of the claimed utility model is: the creation of a safe, easy to operate, environmentally friendly and reliable ultralight aircraft with a maximum take-off mass of not more than 495 kg and a maximum calibrated stall speed (minimum flight speed) of less than 65 km / h.

To solve this problem, a technical solution is proposed, according to which the apparatus consists of a rectangular supporting frame. The frame is made of round and square aluminum metal. The nodes of the frame are fastened by welding and bolted joints. Eight brushless electric motors, two in each corner of the frame, are rigidly attached to the corners of a rectangular frame. Electric motors are installed so that the axis of the shaft of the electric motor is perpendicular to the frame of the apparatus. In pairs installed electric motors are mounted one up by the output shaft, the second down by the output shaft. For each electric motor, two, three or four-blade propellers are made made of composite materials (for example, carbon fiber). The propellers are installed so that the upper one is pulling, directed upward, and the lower pushing one and directed upwards, while the direction of rotation is multidirectional, this is necessary to compensate for the torque. The plane of rotation of all propellers is horizontal. The pairwise mounted electric motors with propellers are placed in a protective ring housing made of composite materials (for example, carbon fiber), as an impeller. In the upper part of the frame, closer to the nose of the aircraft relative to the geometric center of the frame, are located the controls of the device, eight electronic speed controllers, one for each electric motor, two horizontal stabilization units, rechargeable batteries. In the upper part of the frame, closer to the rear of the aircraft relative to the geometric center of the frame, the pilot's seat is equipped with five-point seat belts, two storage compartments, an arc, a battery charger. The fuselage and the landing place of the pilot are made of composite materials with a frame made of aluminum metal.

Depending on the destination, different options are possible for the placement of additional batteries, a small gasoline generator for recharging batteries in the field, the size and location of storage boxes. Also available with a plastic roof for flying in the rain.

Two horizontal stabilization units are configured equally and pre-calibrated so that the first unit repeats all the actions of the second (i.e., for example, when the speed of the two upper right electric motors increases, the first horizontal stabilization unit, the second horizontal stabilization unit also increases the speed of the two lower right electric motors), thereby the horizontal system stabilization is duplicated and the necessary fault tolerance of the equipment is provided.

To increase stability in the “hovering” mode above the ground, an arrangement of electric motors with propellers installed at an angle of two to four degrees to the axis of the frame is possible. That is, the four right-hand motors are arranged so that the axis of the electric motor shafts are not perpendicular to the frame, but at an angle of eighty-six or eighty-eight degrees. Four left motors are located similarly.

Two horizontal stabilization units are installed on the aircraft, the first controls the four upper electric motors located at the corners of the rectangular frame, and the second four lower electric motors located at the corners of the rectangular frame. Two blocks are needed to duplicate vital aircraft systems. Each horizontal stabilization unit is equipped with a controller and three main sensors: accelerometer, gyroscope, barometer. It is also possible to install additional sensors, such as an ultrasonic range finder, speedometer, current control sensor, temperature sensor for engines and batteries.

The aircraft is controlled by changing the speed of rotation of the propellers, which allows it to move up, down, right, left, and rotate around its axis. All engines are installed motionless and rigidly attached to the frame. The angle of attack of the propeller blades (pitch) is fixed. Two horizontal stabilization units receive signals from sensors and controls, and issue a control signal to electronic speed controllers, which in turn change the speed of rotation of electric motors. Electric motors changing their rotation speed thereby changing the speed of rotation of the propellers and traction created by the propellers. Thus, the aircraft maintains a horizontal position.

Effect: the claimed utility model provides a safe, easy to operate, environmentally friendly and reliable ultralight aircraft with a maximum take-off weight of not more than 495 kg and a maximum calibrated stall speed (minimum flight speed) of less than 65 km / h.

Implementation of a utility model:

The technical result is achieved due to the fact that the claimed design of the aerobike contains a supporting frame of a rectangular shape (Figure 3 p. 12), eight brushless electric motors are rigidly attached to the corners of a rectangular frame (Figure 2 p. 5; p. 7), two each every corner of the frame. Electric motors are installed so that the axis of the shaft of the electric motor is perpendicular to the frame of the apparatus. In pairs installed electric motors are mounted one up by the output shaft, the second down by the output shaft (Figure 2). For each electric motor, two, three or four-blade propellers are made made of composite materials (for example, carbon fiber). The propellers are installed so that the upper one is pulling, directed upward (Figure 2, item 4), and the lower pushing one and directed upward (Figure 2, item 6), while the direction of rotation is multidirectional, this is necessary to compensate for the torque. The plane of rotation of all propellers is horizontal. Pairwise installed electric motors with propellers are placed in a protective ring housing (Fig. 1, item 1) made of composite materials (for example, carbon fiber), as an impeller. In the upper part of the frame, closer to the nose of the aircraft relative to the geometric center of the frame, are located the controls of the device (Figure 2, item 10), eight electronic speed controllers, one for each electric motor, two horizontal stabilization units, rechargeable batteries. In the upper part of the frame, closer to the rear of the aircraft relative to the geometric center of the frame, the pilot’s seat is equipped with five-point safety belts (Fig. 1 p. 3), two glove boxes, an arc (Fig. 2 p. 11), a charger for batteries. The fuselage (Fig. 1 p. 2) and the landing place of the pilot (Fig. 1 p. 3) are made of composite materials with a frame made of aluminum metal. On an aerobike, there are various options for placing additional batteries, a small gasoline generator for recharging batteries in the field, sizes and arrangement of glove boxes. Also available with a plastic roof for flying in the rain. The aircraft is controlled by changing the speed of rotation of the propellers, which allows it to move up, down, right, left, and rotate around its axis.

All engines (Fmg. 2 p. 5; p. 7) are installed motionless and rigidly attached to the frame (Fig. 3 p. 12).

The angle of attack of the blades of all propellers (pitch) is fixed.

Two blocks of horizontal stabilization receive signals from sensors and controls (Figure 2, p. 10), and issue a control signal to electronic speed controllers, which in turn change the speed of rotation of electric motors. Electric motors changing their rotation speed thereby changing the speed of rotation of the propellers and traction created by the propellers. Thus, the aerobike maintains a horizontal position.

Two horizontal stabilization units are installed on the aircraft, the first controls the four upper electric motors located at the corners of the rectangular frame, and the second four lower electric motors located at the corners of the rectangular frame.

For takeoff, the pilot, using the controls, launches all eight electric motors. The pilot increases the speed of the propellers until the aerobike is torn off the ground, while two horizontal stabilization units automatically analyze the received signals from gyroscopes and accelerometers and maintain the horizontal position of the aerobike by adjusting the control signal from the controls.

Two horizontal stabilization units are configured equally and pre-calibrated so that the first unit repeats all the actions of the second (i.e., for example, when the speed of the two upper right electric motors increases, the first horizontal stabilization unit, the second horizontal stabilization unit also increases the speed of the two lower right electric motors), thereby the horizontal system stabilization is duplicated and the necessary fault tolerance of the equipment is provided.

To fly in a horizontal position, the pilot, using the controls, changes the rotation speed of the individual engines, which ensures the horizontal movement of the aerobike.

For landing, the pilot, using the controls, slowly reduces the speed of all eight engines, which leads to a slow horizontal decrease. At the same time, the horizontal stabilization unit maintains the aerobike in a stable horizontal position.

To increase stability in the “hovering” mode above the ground, an arrangement of electric motors with propellers installed at an angle of two to four degrees to the axis of the frame is possible. That is, the four right-hand motors are arranged so that the axis of the electric motor shafts are not perpendicular to the frame, but at an angle of eighty-six or eighty-eight degrees. Four left motors are located similarly.

The claimed utility model called aerobike meets modern flight safety requirements, provides the necessary speed and controllability during flight. The presence of a minimum number of moving and wearing parts, as well as duplication of all vital components and parts of an aerobike, provide the necessary fault tolerance. A constant increase in capacity and a decrease in the cost of batteries makes the aerobike a promising individual vehicle.
