HopFlyt Channels the Custer Channel Wing

HopFlyt is an enthusiastic young organization devoted to renewing the Custer Channel Wing, a lost remnant of attempts to create extremely short takeoff and landing (STOL) airplanes starting over 70 years ago.  Their web site explains their primary goal, which includes adding electrically-powered vertical takeoffs and landings to the channel wing’s repertoire. “HopFlyt is an aviation technology startup company [whose] main priority is to develop technology and ultimately build a sustainable electric Vertical Takeoff & Landing (eVTOL) aircraft. The goal of this aircraft is to help you beat the jam of traffic and reduce pollution in major urban centers around the world. We want to change your 2 hours of traffic into a short 20 minutes of flying.” Willard Custer’s …

Pneumatically Pumped Up

Robert J. Englar is Principal Research Engineer at the Georgia Institute of Technology’s Georgia Tech Research Institute in the Aerospace & Acoustics Technology Branch. Responsible for research project direction and development of advanced technologies in aerodynamics, he added a different type of discipline to those presented at the fifth Annual Electric Aircraft Symposium last April in Santa Rosa, California. His research combines attempts to achieve low noise, high lift and short takeoff and landing (STOL) capabilities while applying pneumatic power to the equation. Not to be confused with inflatable rafts, pneumatic, in this case, refers to the careful routing of high-pressure airstreams over very different airfoil and high-lift device surfaces, and has led to measured coefficients of lift in the …
