Core Product Advantages

SW400Pro‑K is a high‑performance civilian‑grade miniature turbojet power unit, suitable for medium‑large‑size heavy‑load fixed‑wing aircraft, heavy‑duty civilian unmanned aircraft and high‑speed aerial‑survey equipment. It delivers stable and powerful 40‑kg thrust and supports flexible parameter adjustment to satisfy diverse operating‑environment demands. Its major advantages are listed below:

1. Stable 40‑kilogram Rated Thrust

The turbojet provides sufficient power for medium‑large‑size aircraft take‑off, rapid climb and long‑distance high‑speed cruise, well‑adapted for heavy‑load aerial‑photography, terrain mapping and long‑range inspection missions.

2. Compact‑Size Light‑Weight Structure

With outer diameter 148 mm, overall length 341.1 mm and net‑weight 3240 g, the reasonable dimension design facilitates body installation and balances the whole‑machine weight.

3. Wide‑Range Adjustable Rotational‑Speed

The working rotational‑speed scope covers 35000‑97000 rpm. Operators can switch between low‑speed cruise and high‑speed flight modes for multiple‑type mission scenarios.

4. Flexible and Comprehensive Adjustable Parameters

Rich startup, running and motor‑control parameters can be customized, which makes the engine compatible with assorted aircraft platforms and fuel‑supply structures.

5. Aviation‑Kerosene Fuel and Low‑Frequency Maintenance

Ordinary aviation kerosene works as fuel, matched with 3%‑5% dedicated lubricating oil. The routine maintenance cycle reaches 25 working hours to lower the long‑term operating expense. Short startup time within 30 seconds brings convenient operation.

Product Overview

1. Product Positioning for Medium‑Large‑Scale Civil Fixed‑Wing Aircraft

SW400Pro‑K is a mature miniature turbojet power source designed for civilian unmanned aircraft and large‑size model jets. Compared with piston gasoline engines, the turbojet owns fast throttle reaction, outstanding high‑altitude adaptability and premium high‑speed flight capability. It is widely used for long‑range aerial mapping, high‑speed aerial recording and medium‑large‑capacity transport unmanned‑air‑vehicles.

2. Physical Index and Flight‑Performance Parameters

Maximum thrust reaches 40 kg, casing outer‑diameter 148 mm, full length 341.1 mm and net‑weight 3240 g. Idle speed is 35000 rpm and the top working rotational‑speed hits 97000 rpm. Rated exhaust temperature is 750℃, and the maximum fuel consumption is kept ≤1000 g per minute under standard working‑state. The engine can finish startup within 30 seconds.
