On March 28, Pipistrel rolled out its prototype Panthera, a sleek four-seat cruiser destined to be the first production hybrid aircraft and eventually, Pipistrel’s second four-seat electric airplane. It is currently powered by a Lycoming IO-390, 210 horsepower engine. At Pipistrel’s factory in Ajdovscina, Slovenia a team of engineers and technicians fired up the engine for the first time and performed ground runs, “verifying design parameters and engine operation.” Pipistrel’s press release quotes Ivo Boscarol, their CEO: “It is very exciting to witness the tests and see the aeroplane come to life for the very first time. This is definitely a very important milestone in the development of Panthera. We look forward to the continuation of tests and the first flight soon!” With the Lycoming powerplant, Panthera can take four people 1,000 nautical miles (1,150 statute miles while cruising at 200 knots (230 mph) and burning 10 gallons of avgas per hour – 92 passenger miles per gallon. While not …
Bye Aerospace Provides Stratospheric Persistence
George Bye, founder and head of Bye Aerospace, introduced the Silent Falcon unmanned aerial vehicle earlier this year at the Association for Unmanned Vehicle Systems International (AUVSI) meeting. He has two other relatively low-cost but highly capable offerings which could stretch the limits of unmanned aerial system (UAS) capabilities. The first, the Starlight program, involves lifting a variable geometry, solar-powered airplane to great heights with a balloon, hovering with it for up to four months, and releasing it when needed to allow refurbishing, refitting and relaunching. This two-stage system provides the same kind of surveillance offered by a satellite, but at a much lower cost. The balloon is a static device, used only to provide the altitude necessary, and the aircraft needs to provide power sufficient to allow station keeping and run its sensor systems for the period it is at altitude. When launched, the nose and tail-mounted electric motors power the airplane on its way. It can slide its …
Pantera Rollout at Friedrichshafen
Friedrichshafen is the place to be for new aircraft announcements, with PC-Aero yesterday and Pipistrel today showing off new aircraft. Pipistrel, having won the Green Flight Challenge in September, could not rest on its laurels, today sharing the news that, “The revolutionary 4-seat all composite design, featuring retractable undercarriage, 200 kts cruising speed, 1000 NM range, comfortable cabin and a choice of three powerplants – conventional/hybrid/electric – is presented to the World for the very first time.” Those lucky enough to be at Aero 2012 , hall A5, will doubtless flock to see the Pantera, a graceful design that does 200 knots (230 miles per hour) on its 200-hp, Lycoming IO-390 engine while burning 10 US gallons per hour. This relative fuel economy (a recent Mooney ride saw the airplane consuming 16 gallons per hour at a lower speed) allows Pantera to carry four people 1,000 nautical miles (1,150 statute miles). CEO Ivo Boscarol is obviously proud of his new …
