Jetoptera’s flight demonstration using Ceramic Matrix Composites prompts invitation to Ceramics Expo 2020

The Ceramics Expo event this year went virtual. Our CEO/CTO Andrei Evulet was invited to participate in the panel 'Addressing the Challenges of Ceramic Matrix Composite (CMCs) Commercialization' panel, now available on demand:

Jetoptera’s patented Fluidic Propulsive System™ will benefit significantly from the introduction of ceramic matrix composites to its turbo-compressor driven product line. Most Vertical Take-Off and Landing (VTOL) small Unmanned Air Vehicles (UAV) today use propellers or rotors driven by either an electric motor or an internal combustion engine or a hybrid combination thereof. Jetoptera’s roadmap includes introduction of CMCs to the hot gas path and thermal recuperator components of the turbo-compressor system, to achieve unprecedented small gas turbine efficiencies while being lighter than piston engines and their hybrids. The increased firing temperatures and the recuperative cycles Jetoptera plans for the FPS over the next five years are enabled by the introduction of CMCs to the combustor, turbine and recuperator; CMCs will reduce the current specific fuel consumption by more than 30%, making the FPS™ as efficient as legacy systems yet at least 50% lighter in weight. This will allow for larger payloads or more fuel onboard of Jetoptera’s VTOL platforms for increased performance.

Jetoptera is one of a handful of companies that have already achieved flight with CMC components, as demonstrated on our platforms using Oxide-Oxide CMC thrusters fed by a gas generator. Three different platforms have used this type of CMCs manufactured by Walter E.C. Pritzkow Spezialkeramik based in Stuttgart, Germany.

Separately, Jetoptera has licensed from NASA SiC-SiC CMC patents which will be deployed in the Hot Gas Path components of the FPS in the coming years. Both non-rotating and rotating components are projected.

Our CEO/CTO Andrei Evulet was joined by Richard White from Lucideon, Jonathan Blank from GE Aviation and Shay Harrison from Free Form Fibers LLC, all offering their insight into topics such as CMC commercialization challenges in Aviation, interfaces with non-ceramic components, and opportunities of Ox-Ox and SiC-SiC based CMC's, among other topics.

"Pigs will fly before ceramics will ever fly", Jonathan heard someone saying a decade ago, "but I'm here to tell you, better watch out for some pigs cause ceramics are flying".

“I am very excited about the potential of additive manufacturing of CMC components in the future” Andrei said. “Particularly when used around interfaces to metal components, this technology is coming, and it will be a game changer for small and larger gas turbines.”

The event is held annually and is hosted by NASA.

About Jetoptera

Jetoptera’s vision is to create a world where aerial mobility is commonplace for both cargo and people. We have developed a unique propulsion system integrated with a novel airframe. This allows us to create lighter, more efficient, and less complex aircraft. Our technology enables vertical and short takeoff and landing (V/STOL), high speeds, sizable payloads and range, and maneuverability.
