TEI-PG50

TEI-PG50 is a two-stroke gasoline aircraft engine developed by TUSAŞ Motor Sanayii A.Ş. (TEI). Designed for unmanned aerial vehicles (UAVs), the engine stands out in Türkiye’s defense industry as a product of the national technology initiative. It distinguishes itself within its class through a high power-to-weight ratio, light weight, and altitude capability.

Development and Serial Production Process

The TEI-PG50 was developed as part of Türkiye’s objective to reduce dependence on foreign engines for UAVs. Emerging from TEI’s research and development efforts in piston aircraft engines, the engine was designed with support from the state’s national technology policies. Among the various aircraft engines developed by Türkiye’s defense industry over the past decade, the TEI-PG50 holds a unique position.

In a study published by TÜBA, it is emphasized that the TEI-PG50 represents a significant milestone among TEI’s piston engines, offering an original design within the category of gasoline-powered engines.

Technical Specifications and Performance

The TEI-PG50 is a two-stroke boxer-type piston engine. With a dry weight of approximately 19 kilograms, it produces around 50 horsepower at takeoff. This power output is defined with a tolerance of ±2 horsepower. The engine’s operational altitude is approximately 16,000 feet.

Equipped with electronic ignition and fuel injection systems, the engine enables precise power delivery through a specialized clutch system. This feature allows UAVs to manage power requirements more efficiently during missions. The engine’s high power-to-weight ratio contributes to effective performance even on lightweight platforms.

Applications and Advantages

The TEI-PG50 is designed to meet the needs of light and medium-class unmanned aerial vehicles. Its gasoline-powered configuration offers advantages over electric motors due to higher energy density, enabling longer endurance flights. Its altitude capability and power output allow UAVs to operate across a broader mission spectrum.

Being domestically developed, the engine also provides advantages in maintenance and logistics. Spare parts supply, servicing, and engineering support are available within Türkiye, making it strategically significant for national autonomy.

Strategic and Industrial Significance

The TEI-PG50 is one of the key steps Türkiye has taken toward developing indigenous solutions for aircraft engines. It holds strategic value for the defense industry and aims to enhance TEI’s technical expertise in engine design and manufacturing.

The engine’s readiness for serial production indicates its potential for integration into various UAV projects in the near future. As a result, it is expected to find wide application in both commercial and military programs.
