TWXN-A22 vertical take-off and landing drone

I.Model Introduction

TWXN-A22 vertical take-off and landing fixed-wing UAV independently developed and manufactured by Beijing Taiweixinnuo Technology Co., Ltd. is a domestically leading high-security, long-flight industrial-grade UAV. This model was designed with high security as the starting point, and adopts dual rudders, coaxial dual motors, dual redundant flight control, electronic injection dual-cylinder gasoline engine, dual power supply system, and other measures to make all systems related to flight safety dual redundant. It minimizes the possibility of system failure and provides customers with a reliable and reliable platform for carrying valuable equipment.

TWXN-A22 adopts a "fixed wing + multi-rotor" composite wing configuration. During the take-off and landing phase, a four-axis 8-propeller multi-rotor is used to provide lift and control. After entering level flight, the multi-rotor stops and enters the fixed-wing working mode, combining the advantages of multi-rotor vertical take-off and landing and fixed-wing large load and long flight time. The hovering power adopts a redundant design, and it can still fly safely in the event of failure of two motors on different axes.

The aerodynamic layout is a sub-fuselage + high-mounted door-type structure tail layout. The central main fuselage is used to install flight avionics equipment, mission payload, fuel tank, and cruise power. The sub-fuselage integrates the vertical tail design to optimize aerodynamic performance. The hovering power and battery pack are installed in the sub-fuselage. The wing is a high lift-to-drag ratio and high aspect ratio straight wing with high cruise efficiency.

The whole aircraft adopts composite material skin hard shell structure, and the fuselage structure is light. There is a modular load compartment at the bottom of the fuselage, which can carry different mission loads according to needs.

III.Features

1．Hovering power four-axis eight-propeller, single propeller failure attitude controllable

When a single motor or even two motors on different axes fail simultaneously during take-off and landing, attitude control and lift requirements can be guaranteed to the greatest extent.

2．Redundant power supply for hovering, attitude controllable in case of single battery failure

Two independent power supply circuits increase the power supply capacity while ensuring no losses due to power supply failures.

3．Adopts electronic fuel injection twin-cylinder gasoline engine, which can work stably in various environments

Compared with single-cylinder gasoline engines, two-cylinder gasoline engines have the advantages of less vibration and stable working conditions. Smaller mechanical vibration creates a better working environment for the avionics system. The fuel injection system makes the engine working condition stable and can adapt the air-fuel ratio to different altitudes during flight.

4．High wing load design, wind resistance level 7 (actual flight)

The smaller wing area avoids the impact of airflow disturbances during flight; at the same time, the solid structural design inherited from the military design concept makes the TWXN-A22 have better wind resistance and overload resistance than aircraft of the same level.

5． Fault-tolerant flight control system design, ten years of experience

Using military-grade components and after ten years of research and development, the TWXN-A22 has accumulated a total of about 4,000 hours of safe flight records.
