Most Interesting Formation Flight at Oshkosh? Perlan 2, its Grob Egrett tow plane, and sponsor Airbus gave AirVenture 2022 attendees a glimpse of future records and promising technology.  Few people outside the Perlan Project have witnessed these two-planes flying in close formation, linked by a tow rope. Initial attempts to get Perlan to an altitude where it could catch high-level mountain waves were hampered by the relatively slow climb of the conventional high-wing craft. Because Einar Enevoldson, founder of the Project, had been a test pilot for the Grob aircraft works in Germany, he had reached a record altitude of 60,867 feet in their Stratos 2C, a twin-engine research craft powered by triple-supercharged Teledyne engines.  The Stratos is the highest …

Too Similar Not to Have Joined Forces The PRNewswire.com press release lauds the acquisition of Airflow.aero by Electra.aero: “Hybrid-Electric Blown-Lift eSTOL Plane Developer Electra Acquires Airflow to Create a Leader in Advanced Air Mobility.”  The two companies have been developing similar multi-motor, blown-lift aircraft for the past few years.  Electra’s has eight motors distributed across its wingspan, Airflow’s has 10. They both use large multi-element flaps to divert propeller thrust downwards, enabling extremely short takeoffs and landings. A Great Idea, but Better with Electric Power This is not a new concept, having been demonstrated in the 1960s by French manufacturer Breguet and American McDonnell.  The 188 was a demonstrator that didn’t pick up any orders in either country.  The narrator …
