Engineered for precision, durability, and effi ciency, our pistons are designed to withstand extreme operating conditions while optimizing power output and fuel effi ciency.
Strict rules regarding security regulations have made it possible for major manufacturers and companies in the industry to meet in person.
Hirth was also present as a partner of the parent company UMS Skeldar and was thus able to establish contacts with international customers and interested parties. Even if it was complicated and sometimes difficult under the circumstances, this exhibition was definitely a bright spot regarding future Defence and Air Shows.
Technical Data
In UAV applications, the piston in a two-stroke engine plays a particularly specialized role. UAV engines demand lightweight, high-performance propulsion systems, and the piston is central to ensuring consistent and effi cient operation over extended fl ight durations.
Key Technical Features
- Advanced Materials for High-Performance Applications
Hirth pistons are crafted from high-strength aluminum alloys, selected for their exceptional thermal resistance and low weight. These materials ensure the piston can endure the high temperatures and pressures generated during combustion while minimizing the engine’s overall weight—an essential factor for UAVs and aviation applications. - Optimized Geometry & Surface Coatings
Precision-engineered piston geometry and surface treatments reduce friction, minimize wear, and enhance overall efficiency. Innovations such as ceramic coatings and low-friction skirts improve heat dissipation and durability, extending engine lifespan while maintaining peak performance. - Sealing & Efficiency for Maximum Power Output
The piston’s interaction with the cylinder walls and piston rings is crucial for maintaining a tight seal, preventing blow-by, and optimizing fuel combustion. This ensures maximum energy transfer to the crankshaft, improving overall engine efficiency and reliability—particularly in UAVs that operate across varying altitudes and temperature conditions. - Fuel Efficiency & Emission Control
By minimizing energy losses and optimizing combustion, Hirth pistons play a key role in improving fuel effi ciency and reducing emissions. These features support compliance with stringent environmental standards and enhance operational economy for UAVs, ultralights, and other aircraft. - Endurance & Reliability for UAV Operations
Hirth continually advances piston technology with enhanced heat dissipation techniques and improved structural integrity, ensuring that UAV engines can meet demanding endurance and performance requirements. Whether for long-range reconnaissance or high-efficiency commercial applications, our pistons are designed to deliver reliability, stability, and power when it matters most.
