U 100 helicopter basic introduction 1. Advantages 1. Engine reliability The U-100 helicopter uses a high-performance horizontally opposed twincylinder two-stroke piston liquid-cooled gasoline engine for aviation . The engine cam is imported from Germany , and the ignition control part is all independently developed . The carburetor and power characteristics are customized for this model . It has low vibration, high power, low fuel consumption, high reliability and long service life. After 418 hours of single-machine flight , the maximum take-off weight can still be greater than 105 kg, which is no different from a new aircraft . The following is a photo of the actual time recorded by the console timer : The following are photos of engine test bench debugging

The engine has its own starting system, which can be started with one button, eliminating the trouble of carrying a starter with you. Remote start can also be installed as needed. The start button has anti-foolproof and speed limit protection to prevent accidental start and sudden rotation of the rotor . The engine has its own power generation system with a maximum power of 230W . In addition to meeting the power supply needs of the aircraft itself , it can also meet the power supply needs of most mission loads, eliminating the need for charging and maintenance of the onboard power supply. The...

control: ① The overall structure and spare parts of the product are designed according to industrial standards . The materials are 7075 aviation aluminum and high-quality alloy steel. The core components such as gearbox, rotor head, tail gearbox, etc. are mass - produced by metal molds , and are all processed by wellknown domestic automobile brands , which greatly guarantees the consistency and reliability of the products : ② Aircraft cables use fully imported high temperature resistant and flame retardant cables specially used for foreign automobiles, bus design, and modular installation to...

③ Aircraft connectors are all waterproof connectors and aviation plugs specially made for foreign cars. Some key connectors are all double- pin redundant structures to ensure high-reliability connection of each electrical component: ④The aircraft electrical main switch adopts a fully imported self-locking button switch with a dual redundant design to ensure the long-term reliability of the switch

⑤ All externally processed parts are required to have a test report from the manufacturer, and 100 % full inspection or trial assembly is required after arrival at the factory to ensure that 100 % of the incoming parts are qualified products and to ensure the quality and consistency of the subsequent assembly : ⑥ There are strict systems and implementation standards for assembly, and the products are assembled in modular form. All assembly stations are carried out according to standardized processes . Each station has an assembly operation manual for the module and a torque table for each screw,...

⑦Each batch of core components must be installed for ground durability testing to ensure the absolute reliability of the product 3. Modular design and disassembly Each component of the product adopts modular design , and each module can be assembled and replaced independently, which can greatly improve the efficiency of production assembly and maintenance ; The tail pipe and landing gear are both quick-release structures. You only need to remove 4 screws to disassemble the entire tail pipe and landing gear ,

which can greatly reduce the difficulty of transportation and packaging size . Ordinary off-road vehicles can be loaded without the need for special vehicles for transportation : The housing is also a quick-release structure that can be quickly opened and disassembled, bringing great convenience to equipment inspection and maintenance :

4. Flight control performance The U-100 helicopter flight control can realize autonomous take-off and landing and autonomous flight at waypoints . The waypoints can be set for hovering time, and the helicopter can also hover at any time during flight through the ground station . Adopting GPS+ Beidou dual-mode navigation and positioning, in the event of GPS loss, the Beidou navigation system can still accurately locate the aircraft, ensuring flight safety and accurate and reliable navigation at any location; The aircraft uses a fully imported digital communication radio that can perform point-to-point...

differential positioning base station, which is capable of high-precision autonomous positioning. The positioning equipment supports differential data correction to improve accuracy. The helicopter is equipped with a flight recording system (black box), which can download the flight records for review after the flight mission is completed. According to different user requirements, the ground station can output flight altitude, coordinates and other information in real time for reference by user equipment. 2. Some Customer Cases Dual light pod , megaphone , searchlight and air quality detector...
