Electra.aero announced new U.S. patents protecting its hybrid-electric propulsion system for ultra-short takeoff and landing aircraft. The patents cover key components that enable the company’s EL9 to operate from spaces as small as parking lots or soccer fields. This technology promises to connect underserved communities using existing infrastructure.
The patents focus on three main areas. First, a flight path control system manages blown-lift aircraft trajectory through integrated power commands. Pilots select modes like takeoff or cruise, and onboard computers adjust thrust across multiple electric motors. This simplifies operations compared to traditional aerodynamic controls. Second, a dedicated pilot guidance display provides real-time feedback for precise low-speed maneuvers. Third, a battery disconnect system enhances maintenance, performance, and safety during hybrid operations.
Chris Courtin, Electra’s Director of Technology Development, explained the innovation. “Our distributed propulsion makes motors active flight control elements. This improves precision, reduces pilot workload, and lets ultra-short aircraft fly like conventional fixed-wing planes,” he said. The system uses closed-loop algorithms referencing air data, attitude, and sensors to optimize each propulsor’s output.
Electra’s Blown Lift Technology
Blown-lift technology accelerates airflow over wings using distributed electric motors. This generates high lift at low speeds for takeoffs and landings under 150 feet. A turbogenerator provides continuous power, solving range limits of fully electric designs. The result combines helicopter versatility with fixed-wing efficiency and safety.
Electra’s approach addresses key barriers in electric aviation. Battery energy density limits fully electric aircraft to short missions. Hybrid systems extend range while maintaining short-field performance. The patents protect scalable power management logic essential for FAA certification under Part 23 rules.
The company tested these systems on its EL2 “Goldfinch” demonstrator, which completed hybrid-electric flights. Test flights for the nine-passenger EL9 begin in 2027, targeting commercial service in 2029-2030. This timeline aligns with FAA pathways for novel propulsion certification.
Regional air mobility could transform underserved areas. NASA estimates demand for 4,000 regional aircraft by 2035. Electra’s “Direct Aviation” model uses small fields to bypass congested airports. Early studies show potential time savings of 50-70% for routes under 200 miles.
For context, conventional regional jets require 4,000-5,000 foot runways. Electra claims EL9 performance rivals the Cessna Caravan but with hybrid efficiency. Independent analysis from MIT’s Aviation Lab supports hybrid-electric potential for short-haul routes.
Electra’s UAM and Beyond Strategy
Internally, this strengthens Electra’s position. Competitors like Lilium and Joby focus on battery-electric designs with charging infrastructure needs. Electra’s hybrid path avoids those limits. Visit electricairmobility.news/evtol-startups/ for more on eVTOL leaders.
The patents include US 12,384,550 for flight control, 12,298,151 for pilot displays, and 12,489,181 for battery disconnects. These build on prior IP for distributed propulsion. Electra’s portfolio now protects commercial deployment.
As safety remains central to any aviation operations, Electra’s battery system allows for quick disconnection for maintenance without full power-downs. Power management ensures redundancy across motors, meeting FAA standards for single-point failures.
Market analysts project $1 trillion in urban air mobility by 2040 per Morgan Stanley research. Ultra-short capability expands viable landing sites beyond vertiports. Electra targets cargo and passenger services initially. And for related coverage, see electricairmobility.news/regional-mobility/ that explores infrastructure impacts.
With current benchmarks showing hybrids aircraft autonomy at around 200-300 mile ranges with payloads, this positions Electra for middle-mile logistics and regional hops. The announcements come amid the FAA’s Innovate 28 plan supports novel propulsion certification. Electra aligns with these pathways through modular testing.
