Electra Secures Patents for Hybrid-Electric Aircraft

Electra.aero, Inc., known for its cutting-edge aerospace innovations, has been granted several U.S. patents that secure critical components of its pioneering hybrid-electric aircraft architecture. These patents protect the core enabling technologies of its hybrid-electric propulsion system and flight control mechanisms, which are specifically designed for ultra short takeoff and landing (USTOL) operations. As the company heads towards certification for its ultra short takeoff and landing EL9 aircraft, these patents also ensure that safety and performance standards are met.

Advancing Hybrid-Electric Flight

The patented technologies encompass essential elements that enhance the deployment of electric blown lift, a crucial innovation that boosts takeoff performance. This strategic move protects the unique nine-passenger aircraft, seamlessly integrating electric propulsion with conventional aircraft flight aspects. The patents address several key systems: the flight path control system (US Pat. #12384550), the pilot guidance display (U.S Pat. #12298151), and a battery disconnect system aimed at improving maintenance, performance, and safety (U.S Pat. #12489181).

Chris Courtin, Director of Technology Development at Electra, emphasized the importance of the patent portfolio, stating, "It safeguards our architecture and facilitates the management of power, lift, and energy safety in a scalable hybrid-electric configuration." Unlike traditional aircraft that depend on aerodynamic control surfaces, Electra's innovative approach allows the motors themselves to serve as active flight control elements. This design not only enhances operational precision but also simplifies the pilot's workload, giving the EL9 the capability to operate similarly to any fixed-wing aircraft.

Innovative Controlled Flight

The flight path control mechanism is based on a closed-loop system that enables pilots to easily command the aircraft's flight path angle via a unified power control interface. Instead of managing multiple throttles or switches, a pilot can select a mode—whether for takeoff, cruise, descent, or reverse—and the system dynamically modifies thrust across its numerous electric propulsion units to adhere to the desired flight path.

This is made possible by Electra's blown-lift method, where electric propulsors mounted along the wings quicken airflow to significantly enhance lift at lower speeds. The algorithms running this system continuously optimize thrust from each propulsor, factoring in real-time data regarding air conditions, aircraft posture, and other relevant sensor inputs. Such advanced control over lift and attitude is essential for achieving reliable ultra-short performance without diminishing cruising efficiency.

Practical Hybrid-Electric Solutions

Electra's hybrid-electric design addresses the range and infrastructure challenges that have historically limited fully electric aircraft. The architecture employs a turbogenerator, which consistently delivers power to its distributed electric propulsors, facilitating long-range, payload-capable flights without the necessity for ground charging links. This innovative aircraft can perform ultra short takeoffs and landings in less than 150 feet, making use of existing runways, parking areas, or even small fields.

By combining the efficiency of distributed electric propulsion with a hybrid-electric powertrain, the EL9 can deliver performance akin to helicopters while benefiting from the cost efficiency and range of traditional fixed-wing planes. Chris Courtin highlighted that the patents underscore how electric propulsion can be rendered not just feasible, but practical in real-world applications, paving the way for the commercial hybrid-electric certification and rollout.

Path Toward Certification

Electra's EL2 technology demonstrator, which incorporates the company’s proprietary hybrid-electric propulsion system, has successfully completed flight tests. As Electra continues to finalize software and power management logic, it is making strides towards the commercial launch of the nine-passenger EL9 Ultra Short aircraft.

Through the introduction of the EL9, Electra is spearheading Direct Aviation, a transformative concept in regional air mobility designed to maximize existing infrastructure and enhance connectivity for underserved communities. The initial test flights are slated for 2027, with full certification and commercial service launch expected around late 2029 or into 2030, aligned with FAA Part 23 regulations.

Currently, Electra has secured over 2,200 pre-orders from 60+ commercial operators worldwide, establishing the EL9 as one of the most promising entries in the advanced air mobility (AAM) market.
