The APD-13 engine is characterized by optimal fuel consumption and is capable of providing UAV flight at an altitude of up to 3,000 m.
The United Engine Corporation of Rostec State Corporation presented the latest APD-13 piston engine for civilian drones at the INNOPROM International Industrial Exhibition in Yekaterinburg. The 13 horsepower plant has already passed ground and flight tests. The M105 small aircraft powerplant is also on display. The product is in the final stage of obtaining a developer's certificate from the Federal Air Transport Agency.
Promising UEC engines are presented at the stand of the Russian Ministry of Industry and Trade at the INNOPROM industrial exhibition. The developments expand the range of power plants for civilian unmanned aerial vehicles and small aircraft.
The two-stroke, two-cylinder, air-cooled aircraft engine APD-13 has been developed using advanced technologies and solutions. With a weight of 3.4 kg and relatively small dimensions, the APD-13 has a power of 13 horsepower. The working volume is 130 cm3 with a stroke of 37.5 mm. The power plant is capable of providing flight of civilian UAVs at an altitude of up to 3000 m.
"A large cooperation of Rostec State Corporation enterprises is working on the development of unmanned systems. The task of the UEC is to provide colleagues with reliable, efficient and inexpensive power plants. The prototype APD-13, created by the corporation's specialists, passed a set of ground and flight tests, including on the test stand, demonstrating reliable operation in the entire range of operating modes and confirming technical characteristics that are not inferior to foreign analogues. This year we also plan to expand the range of aircraft piston engines by creating a 6 horsepower power plant," said Yuri Shmotin, General Designer of the UEC.
The APD-13 engine has an optimal fuel consumption. Thanks to the external mixing, the load on the cylinders is reduced, a high level of environmental friendliness and effective regulation of fuel consumption in different modes are ensured. The use of forced spark ignition guarantees reliable start-up and flexibility in power management and efficiency, as well as stable operation at different speeds.
In addition, the INNOPROM exhibition presents a more powerful piston engine M105, designed for installation on civilian light aircraft and gyroplanes. The product has competitive technical characteristics and is capable of import substitution of foreign analogues.
The M105 is a compact injection four—stroke four-cylinder turbocharged aviation piston engine with a capacity of 115 horsepower. It has a mass of only 75 kg with a working volume of 1211 cm3 with a piston stroke of 61 mm. Among its advantages are operational characteristics. Thanks to the use of advanced design solutions, the engine will be able to operate as part of aircraft for 10 years, with an assigned service life of 2,000 hours and an inter—repair service life of 750 hours. UEC is currently completing work on obtaining a developer's certificate from the Federal Air Transport Agency.
The INNOPROM International Industrial Exhibition is taking place from July 6 to July 9, 2026 in Yekaterinburg. The organizers are the Ministry of Industry and Trade of Russia and the government of the Sverdlovsk region. The financial partner of the exhibition is NOVIK Bank, part of the RT-Finance holding company of Rostec State Corporation. The United Engine Corporation, Uralvagonzavod Concern, KRET, High-Precision Complexes, Rosel, Shvabe and other enterprises will present their products at the joint Rostec exposition.
