Hirth’s state-of-the-art two-stroke engines offer excellent power-to-weight ratios and low fuel consumption, making them ideal for the needs of unmanned aviation.
All products are developed by a team of highly experienced experts at the company’s research and technology facility near Stuttgart, Germany, and every single component, whether manufactured in-house or by vendor partners, is subject to rigorous testing.
Hirth has developed a custom electronic direct injection system that provides unparalleled fuel consumption and smooth-running characteristics, as well as a range of other benefits for UAV platforms. The company’s product range offers options for gasoline as well as heavy fuel engines for UAVs, providing solutions for commercial, military and maritime applications alike. All base engines can be customized and adapted to create bespoke solutions that meet your unique UAV propulsion requirements.
The air-cooled 23 Series is ideal for UAVs weighing up to 120 kg, delivering 50 HP with an unmatched power-to-weight ratio. Engineered to provide superior reliability, it offers a 1000-hour TBO and can be equipped with a range of options including dual ignition, fuel injection, and an electric starter.
Providing 65HP with industry-leading power-to-weight ratio, the 32 Series of air-cooled engines is ideal for weight-constrained UAV platforms. It provides a 1000-hour TBO at 75% power, and ensures that your design is future-proofed against all unmanned aviation challenges.
Weighing just 12.7kg with 30HP of output power, the air-cooled 33 Series is an excellent choice for smaller UAV platforms. It can be optionally equipped with dual ignition, and can also be configured to provide 50W of generator power.
With liquid cooling and exceptional durability, the 35 Series offers the maximum possible power-to-weight ratio available on the 70-horsepower market. It can be optionally equipped with dual ignition, an electric starter, and separate lubrication system.
A heavy-fuel variant, the 35HF, is available to suit the requirements of maritime applications and defense forces.
Based on a proven design that has flown over 20,000 real-world missions in the most demanding environments, the air-cooled 41 Series offers the latest in two-stroke UAV engine technology. Utilizing advanced closed-loop control and automatic altitude and temperature compensation, it delivers up to 8.1 HP at 6700 rpm and ensures ultra-reliable performance under extreme environmental conditions.
Like the 41 Series, the air-cooled 42 Series incorporates advanced closed-loop control and automatic altitude and temperature compensation for optimal performance under any conditions. Delivering up to 15HP at 6500 rpm, it can be equipped with oil injection, various reduction drive options, and starter/generator capabilities of up to 1 kW.
A heavy-fuel variant, the 42HF, is available to suit the requirements of maritime applications and defense forces.
