helicopter tug glider launch

[M B]

The regs seem to simply require experience while'towing a glider with an aircraft' and the U.S.regs don't seem to care what kind of aircraftis used. Tow with a blimp? Don'tthose things go something like maybe twentyknots tops? While towing gliders I've been quite concernedabout my 'noodle.' Yes I've been concernedabout catching on a runway light, rope in theprop during taxi, etc. But the idea of therope snapping back and wrapping the elevatoror rudder in flight has been a concern both as a towpilot and as a glider pilot. Prettyremote possibility, but a good reason fora nice weak link at the end of the towrope.Towing in a helicopter? My goodness! Thiswould REALLY scare me. Towrope in the rotor blades? Yikes! Did they have somethingweighty on the end of the towrope?Mark Boyd

I have read a report once in a (danish) gliding magazine, I think it was
from them World chamoinships once held in Lezno, Poland. the glider was a
Foka type. the trick is that you start with a tailglide.

WGC 1995 in Omarama NZ

the ASW24 started behind a Hughes 500 in low tow
accelerating to 120km/h
after reaching a height of approximately 500m AGL
the helicopter transited into vertical climb and the
ASW-24 just hanged on its Tost hook (attached to
the main wheel) upside down.
The glider pilot then released and came to safe airspeed
as if he would have lost speed just short of topping
a loop.

PS: the guys checked with Gerhard Waibel (the designer
of the Schleicher glider, if it would be safe to strain the
towing hook and the airframe in that way.

just as long as it did not back release... "ouch"

I believe the Royal Navy experimented with towing with
a helicopter in the 60's. If I recall rightly the main
problem mentioned, apart from maintaining separation
between ropes and rotors, was keeping the glider out
of the turbulence created by the helicopter. This needed
about half a mile of towrope.

I will tow you. price is $700 per hour. figure 8 minutes to start and get
hooked up and five minutes for tow and 8 mintues to land an shut down. Maybe a
tow by airplane is more cost effective?

I think that the tow started as a traditional tow.

Bob Carlton (Silentwingsairshows.com) is currently doing about three
hellicopter tows a year with his Salto, although it's not as most of you are
imagining it. The hellicopter has 10 ft of chain dangling under it which the
rope is attached to. He lifts off and flies forwards and the glider does a
normal take off followed by a basicly normal tow.
