EDMONDS, Wash., Feb. 17, 2023 (GLOBE NEWSWIRE) — Jetoptera is getting thrilling ends in the wind tunnel! In assist of our USAF sponsored Section II Small Enterprise Know-how Switch (STTR) program, Jetoptera labored with AeroTEC and Scaled Composites to design and construct an engineering check article mannequin particularly for wind tunnel testing. Jetoptera sub-contracted the College of Washington and the Kirsten Wind Tunnel group to hold out these assessments. Our CEO, Andrei Evulet acknowledged: “We accomplished our wind tunnel check marketing campaign below our fifth US Air Pressure contract. The outcomes assist our proprietary resolution of a Excessive-Velocity Vertical Take-Off and Touchdown (HSVTOL) automobile utilizing the “3-in-1” Adaptive Fluidic Propulsive System (FPSTM). In collaboration with Pratt & Whitney GATORWORKS®, the automobile is a single-engine design based mostly on a Pratt & Whitney turboshaft engine driving a high-performance compressor that may carry out Vertical Take Off and Touchdown (VTOL) and is predicted to achieve twice the pace of tilt rotor plane in ahead flight. The present STTR Section II program validates the expected efficiency of this HSVTOL plane idea. Individually, Jetoptera stays considered one of a handful of corporations concerned with the HSVTOL Problem Program launched 2 years in the past by AFWERX.”

Our Adaptive FPSTM-powered plane wind tunnel mannequin is a 30% scale of the one engine idea developed below a 2022 Direct to Section II Small Enterprise Innovation Analysis (SBIR) Program, on which we teamed with our subcontractor, Scaled Composites. We predicted the 5000 lbs Vertical Take Off and Touchdown plane powered by a single turbocompressor pushed by an present 2500 HP-class turboshaft might be able to speeds of as much as Mach 0.8. The Adaptive FPSTM system and the one engine plane are scalable to bigger functions. This design is only one instance of the novel capabilities FPSTM brings to superior aviation propulsion.

We constructed the 30% HSVTOL wind mannequin with assist from AeroTEC. Additive manufacturing produced 50% of the mannequin parts, together with the compressed air propulsion system – conduits, valves and thrusters. We examined the design at varied wind and compressed-air situations with three configurations involving stowable FPSTM thrusters of assorted sizes, distributed optimally over the wings and fuselage. The three fundamental configurations are VTOL, transition, and high-speed ahead flight (representing the “3-in-1” FPSTM deployment, respectively.) Wind tunnel information collected included forces, moments, pressures, flow-field surveys, and movement visualization. FPS™ and Higher Floor Blown-Wing had been deployed within the powered-lift configuration for VTOL feeding compressed air to our proprietary thrusters (for VTOL and transition to horizontal flight). A Excessive-Velocity Nozzle (HSN) configuration was deployed for the high-speed ahead flight a part of the mission. The assessments lined regimes as much as 200 mph wind at Sea Stage with a measured output of the HSN jet speeds of as much as 700+ mph. Knowledge might be used to help with constructing a 6 Levels of Freedom mannequin and additional discover the flight envelope and the efficiency of the a number of HSVTOL ideas. Jetoptera will even apply the information to develop different ideas starting from Wing in Floor Impact and ISR to massive HSVTOL, Normal Aviation, City Air Mobility, Cargo VTOL plane and FPSTM-powered Parafoils.
