SW400Pro 40‑kg‑Thrust Miniature Turbojet Engine for Civil‑Use UAV

Core Product Advantages

SW400Pro is a high‑performance civilian miniature turbojet power unit, suited for large‑scale fixed‑wing aircraft, heavy‑load civilian unmanned aircraft and high‑speed aerial‑survey equipment. It supplies stable large‑thrust output and comes with a full‑set of matched electronic‑control accessories. Its major strengths are listed below:

Strong 40‑kilogram Rated Thrust
The turbojet engine delivers powerful thrust to support large‑size aircraft take‑off, rapid climbing and long‑distance high‑speed cruise, perfectly fitting heavy‑duty aerial‑photography, terrain mapping and long‑range patrol assignments.
Optimized Compact‑Size Body
With 148 mm outer diameter, 341.1 mm overall length and 3240 g net weight, the streamlined structure saves cabin installation space and cuts down the overall weight burden for the airframe.
Wide‑Range Adjustable Working Speed
The operating rotational‑speed covers 35000‑97000 rpm. Pilots are able to toggle low‑speed cruise and high‑speed flight modes to satisfy diversified mission‑mode demands.
Complete Supporting Accessory System
Standard matched components contain power cable, signal wire, data display, V4‑type ECU controller, oil filter and fuel‑control ball valve. The full control kit enables parameter tuning, real‑time operational‑status monitoring and convenient on‑site debugging.
Convenient Fuel Standard and Low‑Maintenance Cost
This turbojet uses aviation kerosene as fuel mixed with 3%‑5% dedicated lubricating oil. The routine maintenance cycle reaches 25 working hours, effectively lowering long‑term operating expense for civilian aircraft operators.

Product Overview

1. Product Positioning for Large‑Size High‑Speed Civil Fixed‑Wing Aircraft

SW400Pro is a mature miniature turbojet power source designed for civilian unmanned aircraft and large‑scale model jets. Compared with piston gasoline engines, the turbojet features fast response, great high‑altitude adaptability and excellent high‑speed flight capability. It is widely used in long‑range aerial mapping, high‑speed aerial recording and large‑capacity transport unmanned‑air‑vehicles.

2. Physical Index and Flight‑Performance Parameters

The engine provides maximum 40 kg thrust, casing diameter 148 mm, total length 341.1 mm and net weight 3240 g. Idle speed is 35000 rpm and the top operating speed hits 97000 rpm. Its rated exhaust temperature is 750℃, while the maximum fuel consumption is controlled within 1000 g per minute under standard working conditions.

3. Full‑Set Electronic‑Control Accessories

Every complete package is equipped with power‑supply cable, signal transmission cable, display screen, V4 ECU, precision oil filter and fuel‑control ball valve. Operators can configure startup parameters, acceleration‑deceleration curves, speed limits and temperature thresholds via the ECU system.
