CoFlow Jet Aerospace

• We are addressing the following fundamental limitations that affect virtually all current aircraft:
• limited range due to low aerodynamic efficiency;
• small stall margins that restrict the operational flight envelope;
• high noise;
• long takeoff and landing distances; and
• complex and inefficient hover–cruise transition systems for VTOL aircraft.
• CoFlow Jet (CFJ) technology provides a unified solution to all of these challenges.

We are funded by NASA to develop a Martian eVTOL aircraft, the Mars Aerial and Ground Intelligent Explorer (MAGGIE), using deflected slipstream enabled by CoFlow Jet (CFJ) technology. MAGGIE is designed to be powered by solar energy and to achieve global-range mobility over the Martian surface. It will be capable of taking off, flying, and landing virtually anywhere on Mars to support scientific exploration and future human missions. A short video describing the MAGGIE mission is available here: https://www.youtube.com/watch?v=FaauIJkZPy4 The same CFJ-enabled deflected-slipstream technology can be applied on Earth, with the potential to increase eVTOL range by up to 100%.

  Experimental design for a novel co-flow jet airfoil - Advances in Aerodynamics

  SpringerLink

  The Co-flow Jet (CFJ) technology holds significant promise for enhancing aerodynamic efficiency and furthering decarbonization in the evolving landscape of air transportation. The aim of this study is to empirically validate an optimized CFJ airfoil through low-speed wind tunnel experiments. The CFJ airfoil is structured in a tri-sectional design, consisting of one experimental segment and two stationary segments. A support rod penetrates the airfoil, fulfilling dual roles: it not only maintains the structural integrity of the overall model but also enables the direct measurement of aerodynamic forces on the test section of the CFJ airfoil within a two-dimensional wind tunnel. In parallel, the stationary segments are designed to effectively minimize the interference from the lateral tunnel walls. The experimental results are compared with numerical simulations, specifically focusing on aerodynamic parameters and flow field distribution. The findings reveal that the experimental framework employed is highly effective in characterizing the aerodynamic behavior of the CFJ airfoil, showing strong agreement with the simulation data.
