Introducing the SP-180 SRE Hybrid: A Cutting-Edge Rotary Engine

The SP-180 SRE hybrid represents a state-of-the-art single-rotor engine featuring a 180cc combustion chamber, seamlessly integrated with a starter generator unit. This innovative design is at the forefront of Sky power’s propulsion technology lineup.

Advanced Design and Performance Excellence

As the premier model in Sky Power’s range,the SP-180 hybrid Wankel engine delivers extraordinary performance metrics,achieved through a proprietary,patented internal architecture focused on a single-cylinder 180cc configuration. Thanks to the inherent advantages of the Wankel rotary design, this engine boasts a remarkably lightweight profile and a compact footprint, significantly smaller than comparable two-stroke engines. Its minimal radial and torsional vibrations make it an ideal power source for applications requiring high-precision optics or sensitive sensor equipment.

Versatile Installation and Operational Modes

One of the unique features of the SP-180 is its capability to be mounted vertically at a 90-degree angle, enhancing its adaptability for use in rotary-wing aircraft such as helicopters. The integrated starter generator expands the engine’s functionality, enabling multiple modes of operation:

• Pure Mechanical Drive: Delivers up to 22 kW of mechanical shaft power as the sole propulsion method.
• Hybrid Mechanical-Electric Drive: Combines mechanical output with electric propulsion for enhanced efficiency.
• Electric Power Generation: When paired with an onboard battery system, the engine powers a generator that supplies electricity as the primary propulsion source.
• hybrid Boost Mode: Simultaneous mechanical and electrical power delivery for peak performance demands.

Safety and Reliability Features

The integrated hybrid system also serves as a critical redundancy mechanism, providing emergency descent capability in case of system failures. This feature enhances operational safety, particularly in demanding aviation environments.

Proven Technology with Global Operational Success

Currently at Technology Readiness Level 9 (TRL9), the SP-180 has been extensively flight-tested across diverse environmental conditions worldwide. Its robust water-cooled housing and rotor oil cooling system ensure reliable thermal management. The engine’s maintenance schedule is predictable and streamlined, reducing downtime and maximizing mission availability.
