Propulsion reengineered for unmanned aerial systems
SWaP-Optimized Propulsion System for the evolving needs of the drone platforms.
Our Mission
Stoich Engines builds purpose-engineered engines
Stoich Engines builds purpose-engineered engines for the next generation of Intelligence, Surveillance, and Reconnaissance (ISR) drones. We equip unmanned aerial systems with the critical propulsion necessary for extended range, persistent surveillance, and high-stakes data acquisition.
Our patented engine design, along with advanced combustion strategies, allows us to achieve unrivaled fuel-efficiency, superior reliability, and optimal performance, crucial for the most demanding ISR missions.
Our engine design, uniquely grounded in 3D printing, allows us to significantly lower production costs and eliminate critical supply chain bottlenecks. We are committed to producing the most cost-effective, yet reliable and high-performance engines needed for the evolving battlefield with drones.
Our Core Technology
Engineered for ISR Excellence
At Stoich Engines, our propulsion systems are purpose-built to deliver exceptional performance in Intelligence, Surveillance, and Reconnaissance (ISR) missions. Leveraging advanced design, CFD modeling, and precision manufacturing, we ensure optimal reliability under real-world conditions. With access to a CFR-compliant engine test laboratory, we rigorously validate our engines at the demanding operating profiles typical of drone platforms, ensuring mission readiness and endurance where it matters most.
Improved Brake Thermal Efficiency
Our engine design eliminates friction between key moving parts through an innovative opposed-piston architecture featuring well-balanced piston movement. This near-frictionless operation minimizes energy losses, enabling us to achieve an exceptional brake thermal efficiency of 45%—well beyond conventional engine benchmarks. The result is a more compact, robust, and fuel-efficient engine optimized for heavy fuels.
Reduction in parts and Modular design
Our engine design, made possible through advanced 3D printing, reduces the number of parts by 20%, streamlining manufacturing and enhancing reliability. Its modular architecture enables seamless power scaling by adding engine blocks, making it easily adaptable to higher-power applications without sacrificing efficiency.
