An Ottawa aeronautical engineering consultant, Mr. Rene Charette, has provided Air Pictorial with an exclusive account of his original design for a new-style VTOL (Vertical Take-off and Landing) business executive four-seater. As the general arrangement drawing indicates, the Charette Executive Vertiplane has a cantilever, constant-chord wing featuring NACA aileron-linked slots, spoiler ailerons, endplates and 80-per-cent-span interconnected (with tailplane) wing flaps. This all-metal, fixed quadricycle undercarriage monoplane takes advantage of two outsize airscrews which are connected to a self-priming oil-fed turbine. The only controls will be the throttle and a steering-wheel-type control system. Tests with scale models over the past twelve years indicate that the double-flap system and the "blown wing" of highlift section will achieve 90-degree slipstream deflection and superior lateral control. Mr. Charette suggests that the Executive Vertiplane - which is now being constructed in prototype form - will achieve 150 m.p.h. and have a cruising range of 1,500 miles at 100 miles/gallon. Span 38 ft.; length 25 ft.; height 7 ft. 6 in.
