Is there such a thing as a rocket opening parachute?

In other words a rocket attached to a metal static line that pulls a
parachute
out of a bag and makes it open almost instantaneously?


I am thinking of safe ways of testing a tilt rotor aircraft.

Paul Lamar ...No rotor no motor.

Paul... isn't that precisely what the BRS (ballistic recovery system) is all
about... a ballistic deployment, a slider ring to accommodate fast vs. slow
speed filling of the chute.   ????  am I missing something here???

I am not sure. I don't know how it works.

I would not necessarily like to save the airplane. Just the pilot from
and open cockpit.

Yep,  I still have the rocket and switch from one of the first units BRS
made for an ultralight I brought into Japan 25 years ago.  Never used it.
The solid propellant rocket is about shaped in an aluminum pipe is 1.5
inches in dia and 6 inches long with a rubber nose cone. A kevlar strap
attaches to the chute and to the rockets stainless wire bridle.  You
wouldn't not want to attach this to a person's harness for reasons of sudden
stress and the fact that opening a parachute outside the plane with the
person inside usually results in the person and plane being destroyed.
Better to bring your whole plane down as the pilot has more protection from
the structure.

My brother was lucky last year when he was flying and one of his jump
instructors let her pilot chute go out the open door.  All of her students
gracefully kicked her out of the plane and followed in mass shortly after.
Airplane do not usually survive such an event.  Her partially open chute
took off the C-182'2 right stabilizer and elevator before she was able to
cut away.  Somehow he was able to land safely using a burst of throttle
before contact.

Wow.

I'll have to think this thing through. The big problem is
making sure the rocket points as straight up as possible with out
fouling the rotor. Maybe I need a guidance system of some sort in the rocket.

Hi Paul, didn't the Germans in WWII and later the Soviets tackle this
problem already with the rear prop fighter (DE) and the helicopters with
ejection seats (RU) ? I thought they both had explosive bolts on the
blades for when the pilot bailed.

That sounds good.
