Haery Power's "Skylark" aviation heavy oil piston engine completes initial performance test

In April 2017, Anhui Haery Aviation Power Equipment Co., Ltd. (referred to as "Haery Power") independently developed the aviation heavy oil piston engine code-named "Sunlag" successfully completed its initial performance test. The actual power is not onlyExceed95kw, the peak power reaches 100kw, which not only exceeds the original design goal, but also shows that it has good potential for optimization and improvement. This is another important step forward since the engine was successfully ignited at the beginning of the year, laying a solid foundation for the subsequent successful development and production of the engine.

Currently widely used in ChinaThe 100-horsepower aero piston engines are basically imported from abroad, and are fueled by aviation gasoline. They have poor fuel economy and relatively cost-effective use, and are limited in many areas with demand. In the field of compressed-ignition aviation heavy oil piston engines, domestic products are basically blank. When Haery Power was first established, it aimed to provide more advanced products for the domestic aviation heavy oil piston engine market. Combined with years of experience and technological innovation in the field of engines, it devoted itself to creating advanced products made in China. Although "Skylark" is a heavy oil engine, its technical indicators in terms of power-to-weight ratio, vibration noise, etc. are better than those of foreign gasoline engines.

Haery Power has fully implemented the design concept of safety, trustworthiness, rapid fuel saving, and integrated the more advanced technologies in the international engine field:1. The liquid cooling of the whole machine has a better cooling effect, so that the parts can withstand a better working temperature, increase the service life of the engine, and be applied to a wider range of harsh working environments and conditions; 2. The pressure-reduced common rail can better atomize fuel; electrically controlled injection can quickly control the oil according to demand, so that every drop of oil is fully burned, so that the aircraft has a longer range; 3. Supercharged intercooling and multi-stage supercharge technology will bring more power and lower fuel consumption to the aircraft engine, and better empty performance.4. The redundant design of the FADEC system provides safety and double insurance for the use of the engine.These mature technologies will greatly improve the altitude limit and range of existing aircraft, which is well suited for flightThe development needs of the equipment at a higher altitude and long-distance time.

At last year's Zhuhai Air Show, Haery Power exhibited three aviation heavy oil piston engines and two small horsepower gasoline engines used in the fields of industrial drones and agricultural and forestry plant protection drones.

The "Skylark" aviation heavy oil piston engine has fully investigated customer needs at the beginning of its design. It uses aviation coal and diesel as fuel and can be used for takeoff weight.700About kgrotorcraft andAbout 1.5tFixed-wing drone, at altitude7000m is more powerful, and the power attenuation is less than 30%. After airworthiness certification is collected, it can be widely carried on various aviation manned aircraft, injecting new impetus into the aviation market. At present, a multi-stage supercharged engine based on the "Skylark" and flying ratio up to 25km has also been designed with technical solutions, and the performance prototype will be tested soon.

Without the right oil, it is difficult to promote; without the right power, it is difficult to fly organically. The emergence of domestic aviation heavy oil piston engines has unraveled the shackles that restrict the development of China's aviation industry due to the single variety of aviation power, and the development space of China's aviation industry has become wider since then.

With it as a medium, the efforts of the whole people, Haery Power, looking forward to compose a fresh melody in the field of aerodynamics!
