VTOL fixed wing UAV
Development status of vertical takeoff and landing fixed wing UAV
Vertical take-off and landing (VTOL) is generally referred to as VTOL. Vertical take-off and landing fixed wing UAV refers to the UAV with fixed wing and vertical take-off and landing. It combines the advantages of rotor and fixed wing. It is true that the tilt rotor mechanism enables both vertical take-off and landing and fixed wing speed, but its complex mechanical structure, strict requirements for materials, flight control and even engine make the price extremely high.
Rotor fixed wing compound vertical take off and landing UAV
It is completely different from the original four rotor power unit, which is based on the original rotor power device. In the take-off and landing phase, the rotor device is used, and the conventional fixed wing power unit is used in the cruise phase. Since the two sets of devices are independent of each other, the key technology is to solve the smooth conversion between the two modes.
Advantages and development trend of VTOL fixed wing UAV
The vertical take-off and landing fixed wing UAV overcomes the common problem of limited range and speed of rotor UAV, and gets rid of the disadvantages of the conventional fixed wing UAV, such as tedious and unstable launching and recovery methods, and high requirements for personnel. This kind of characteristic fits well with people's expectation that UAV is more intelligent and convenient, with larger load, less energy consumption, longer endurance and wider range of use. It is because of these advantages that countries all over the world pay more and more attention to vertical takeoff and landing fixed wing UAVs, and various UAV companies have begun to develop various vertical takeoff and landing fixed wing UAVs.
With the development of flight control technology, VTOL fixed wing UAV is becoming more and more smooth and reliable in the mode transition stage. In addition, some open-source flight control systems have been added to the vertical takeoff and landing fixed wing aircraft, so that the public can design and manufacture or transform them. With the development of miniaturization technology, the size of VTOL fixed wing UAV can be smaller. Small UAV with its unique weight advantage, gradually began to have the unique military capabilities of large UAV, and can greatly save costs. As a result, the use of vertical takeoff and landing fixed wing UAV has become more extensive. With the advancement of battery technology, the use of fuel cell or hybrid battery power supply technology makes the vertical take-off and landing fixed wing UAV have longer endurance time, greatly improved flight performance and more competent occasions.
Advantages of VTOL fixed wing
At present, the vertical lift used in the market is rotor type, which combines multi rotor and fixed wing. Therefore, the vertical UAV has the multi rotor take-off and landing mode, which solves the site requirements of fixed wing UAV taking off and landing. At the same time, it has the advantages of long flight distance, fast speed and high altitude of fixed wing, and solves the problem of short endurance, slow speed and low flight height of multi rotor The problem.
Industry application of VTOL fixed wing
Due to its long endurance and large activity radius, it is mainly used in traffic supervision, oil field pipeline inspection, surveying and mapping, forest inspection, and has a broad application prospect.
