Meaning
Long range fixed wing unmanned aerial vehicles are specialized unmanned aerial vehicle platforms that focus on enhancing endurance and flight distance on the basis of conventional fixed wing unmanned aerial vehicles. They generally have ultra long endurance and ultra long operating radius, and can perform cross regional, large-scale, and long-term continuous reconnaissance and task operations. They are the core equipment for remote reconnaissance, border control, and wide area monitoring.
Basic principles
Principle of aerodynamic lift
Relying on fixed wings to generate aerodynamic lift during flight, the fuselage maintains a sustained forward speed to maintain takeoff, consistent with conventional fixed wings.
Efficient Pneumatic Layout
Adopting a high aspect ratio wing and low drag fuselage design to reduce flight resistance and significantly improve energy utilization efficiency.
Efficient power system
Use heavy oil engines, electric long-range power or hybrid power more often, with lower fuel consumption and higher energy density, to support long-term flight.
Attitude and Route Control
Rely on the control surface to control pitch, roll and yaw, and cooperate with the auto drive system to achieve autonomous cruise, automatic homing, and intermittent continued flight.
Main features
■ Extremely long voyage and long endurance
The range can generally reach several hours to tens of hours, with a range of hundreds to thousands of kilometers, far exceeding ordinary drones.
■ High flight efficiency and low energy consumption
Pneumatic layout optimization results in longer flight distance per unit energy consumption.
■ Fast cruising speed and wide coverage area
Suitable for rapid inspection and continuous monitoring of large areas.
■ Strong load carrying capacity
It can mount professional equipment such as high-definition electro-optical, infrared cameras, radars, communication relays, reconnaissance pods, etc.
■ Good wind resistance and stability
Suitable for flying over long distances and under complex weather conditions.
■ There are certain requirements for takeoff and landing conditions
It is commonly used for catapult takeoff, parachute recovery, and slide takeoff and landing, and generally cannot take off or land vertically.
■ Difficult to hover in place
The main focus is on wide area inspections, with weak ability for precise and targeted observation.
