The predicted figures make it quicker than commercial airlines and twice as fast as tiltrotor designs.

The absence of spinning blades is replaced by devices that use fluid dynamics that leverage small amounts of moving air to push through a much larger amount of outside air and generate thrust. A gas generator was used in earlier designs to compress air for the process, owing to its lightweight and being an efficient source of pressurized fluid.

According to the company, the system combines a gas or electric turbine and fluidic thrust augmentation that can distribute thrust across our airframe. "It can be implemented in various geometric shapes, can be embedded with the airframe, and has no propellers or rotating parts. The system is used in all phases of flight."In a first for the company, the current concept, tested for the SBIR contract, featured a high-efficiency electric compressor sourced from outside.

"A separate, ongoing STTR Phase II program will validate its design in the first half of 2023. The maximum speeds predicted for the concept are over twice as fast as a tiltrotor."
