It delivers stable 30‑kg thrust output and is equipped with mature electronic‑control accessories, making it suitable for long‑endurance and high‑speed civilian flight platforms. Its main advantages are as follows:

Stable 30‑Kilogram Rated Thrust
The turbojet engine provides consistent 30‑kg thrust for large‑size aircraft take‑off, rapid climbing and long‑distance high‑speed cruise. It supports heavy‑duty aerial photography, terrain mapping and long‑range inspection missions.
Compact and Lightweight Body Structure
With an outer diameter of 132 mm, overall length of 331.4 mm and net weight of only 2560 g, the streamlined layout saves installation space and reduces the overall load of the airframe.
Wide Adjustable Speed Range
The operating rotational‑speed ranges from 38000 rpm to 98000 rpm. Users can switch between low‑speed cruising mode and high‑speed flight mode to meet different operational requirements.
Complete Electronic‑Control Accessory System
Standard supporting accessories include power cord, signal cable, display screen, V4‑version ECU controller, oil filter and ball valve. The full control kit facilitates parameter adjustment, real‑time status monitoring and convenient field debugging.
Kerosene Fuel and Easy Maintenance
This turbojet engine uses aviation kerosene as fuel, mixed with 3%‑5% lubricating oil. The routine maintenance cycle reaches 25 working hours, helping to reduce long‑term operating costs for civilian aircraft operators.

Product Overview

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

SW300Pro‑K is a mature miniature turbojet power unit oriented at civilian unmanned aircraft and large‑size model jets. Compared with piston‑type gasoline engines, the turbojet structure offers faster throttle response, better high‑altitude adaptability and stronger high‑speed flight capability. It is widely used for long‑range aerial mapping, high‑speed aerial recording and large‑capacity transport unmanned aircraft.

2. Main Physical and Flight‑Performance Parameters

The engine features 30‑kg maximum thrust, 132‑mm casing diameter and 331.4‑mm overall length, with a net weight of 2560 g. Its idle speed is 38000 rpm, while the maximum operating speed reaches 98000 rpm. The rated exhaust temperature is 750℃, and the fuel consumption is controlled within 820 g per minute under standard working conditions.

3. Complete Electronic‑Control Accessory Configuration

Every standard package comes with full control components: power‑supply cable, signal transmission wire, data displayer, V4‑model ECU, precision oil filter and fuel‑control ball valve. Operators can adjust startup settings, acceleration and deceleration curves, rotational‑speed limits and temperature thresholds through the ECU system.
