Hirth Engines and ePropelled introduced a strategic collaboration to develop hybrid propulsion options focusing on the UAV, aerospace, and defence markets. The partnership combines Hirth’s decades-long experience in two-stroke engine expertise with ePropelled’s clever electrical propulsion and power-management programs.
Technical Specs of Hybrid Propulsion Integration
The hybrid propulsion programs will combine Hirth’s high-performance two-stroke engines with ePropelled’s starter-generators and digital engine starters. This strategy merges mechanical energy technology with superior electrical programs, addressing demand for light-weight, energy-efficient propulsion in demanding purposes.
Hirth is bringing their 3508HF to the desk, a variant inside the Hirth 35 collection of liquid-cooled, two-cylinder, in-line two-stroke engines designed for UAVs and lightweight plane. The 3508HF options heavy gas functionality, offering operational flexibility for navy and industrial UAV purposes the place jet gas compatibility is required.
In response to the businesses, the hybrid propulsion options will ship important fuel-efficiency positive aspects, prolonged flight length and payload capability, and decrease lifecycle working prices. The programs are designed to offer enhanced reliability and redundancy for mission-critical purposes whereas enhancing sustainability to fulfill rising regulatory requirements.
The partnership emphasizes superior power-to-weight ratios and reliable efficiency, important specs for UAV operations in difficult environments. Bruno-Gerard König, CEO of Hirth Engines, acknowledged: “This partnership elevates what our engines can obtain and opens new alternatives in fast-growing sectors resembling UAVs and superior air mobility. ePropelled’s expertise completely enhances Hirth’s heritage of engineering excellence.”
UAV Purposes and Improvement Timeline
The collaboration targets a number of purposes together with UAVs and uncrewed programs, superior air mobility platforms, defence and surveillance missions, and industrial aerial purposes. Nick Grewal, CEO & Founding father of ePropelled, commented: “Combining our clever electrical power-generation programs with Hirth’s world-class engines permits us to ship hybrid options that set a brand new benchmark for efficiency and effectivity. This collaboration accelerates the way forward for hybrid propulsion.”
Analysis, improvement, and system-integration work are underway, with prototype demonstrations anticipated in upcoming venture cycles. The businesses plan to showcase prototypes at UMEX in Abu Dhabi in January 2026, offering business stakeholders with alternatives to guage the hybrid propulsion expertise firsthand.
Hirth Engines, primarily based close to Stuttgart, Germany, has almost 100 years of expertise manufacturing two-stroke engines for aviation and UAVs. ePropelled, based in 2018 and headquartered in Laconia, New Hampshire, holds 40 patents in good propulsion and energy-management programs for uncrewed autos.
