include linkages that almost automatically connect aileron pushrods to the control stick linkage.
Instead, a composite and aerodynamically clean (folding) nose-mounted propeller driven by an LZ Design brushless electric DC motor can launch the sailplane
to a maximum altitude of 5000 feet, although most pilots will climb to a lesser altitude to reserve power, unaffected by density altitude, of course.
are using electric motors to get airborne.
It is still occasionally performed with modern recreational sailplanes
World-class hang-glider and sailplane
pilot Geoff Loyns has died at the age of 56.
EDWARDS AIR FORCE BASE - With the graceful flight of hawks and eagles in mind, NASA aerospace engineer Michael Allen hand-launched a lightweight motorized model sailplane
over Rogers Dry Lake, hoping it would catch plumes of rising air called thermals.
Mr Freeman, aged 47, sometimes flies powered sailplanes
over the beach near his home and has launched unpowered hang-gliders from seaside cliffs but has not yet been forced to ditch in the sea at Newbiggin.
In rare spare time, he flies sailplanes
competitively and windsurfs in the frigid waters of lake Michigan.
4-foot variable-pitch propeller is so long that it can't spin until the plane is aloft, so the long-winged robot will be launched like some sailplanes
, that is, pulled by a winch-wound cable until airborne, when the engine will be engaged and the cable detached.
So Perseus will take off in the manner of some sailplanes
, pulled forward with the help of a winch-driven cable until it's airborne, at which time the motor will engage and the cable will release the craft.
You'll pass docile cows and cross cattle stiles; at the top, sailplanes
may soar overhead and the South Bay lies before you like a relief map.
During this years edition of AERO, the biggest GA trade fair in Europe, held in Friedrichshafen, Germany, EASA presented several strategic key objectives of the GA Roadmap which have already been reached: alleviations for training schools and better access to Instrument Flying for GA pilots, the stand-alone OPS rules for Balloons and Sailplanes
, the single set of rules for specialized operations, simplified maintenance rules and specifications for changes and repairs.
