hillberg,
Substation or not, it won't be a problem. The main concern with unmanned operations is undue hazard. Obviously the system being recovered is optimal but not completely a requirement. As far as the chute deploying on the ground (at least that's what I assume you mean)...You have safety pins on the ballistic charge that are removed directly before takeoff :) |
Courtesy of this month's PAN:
Although conventional wisdom suggests that rotary wing craft have their own ‘parachute’ in the presence of the rotor itself, a Czech company has developed a new parachute based aircraft recovery/safety system. Readers may be familiar with the concept of the Ballistic Recovery Systems parachute based system used on such light fixed wing aircraft as the Cirrus, this new system is designed for light rotary craft. Already tested it enables safe recovery of rotary craft from a height of 60m at a forward speed of 60km/h and higher or from 110m if in the hover. Galaxy GRS s.r.o. are to exhibit at AERO Friedrichhafen this month but were walking the halls in Anaheim last month. Fuller details can be found on their website (Lights blue touchpaper and retires quickly... :E) I/C |
Now you take a controled landing into uncontroled landing, Now you have Trees, wires, homes & a childrens birthday party to drop into.
You lose the best part of autorotation "control" the ability to pick a spot & land on a dime, With a chute you get a dime the size of New Jersey. |
I think you may be missing the point Hillberg . Nobody doubts the proven autorotation ..... This wouldn't deploy in an engine failure as there is no violent negative g . It is designed , I guess , to only click in as a very last chance of survival AFTER control has been lost and you are rapidly falling ( as in mast bump / rotor separation , the R22 thing ) . In that situation I would pay a few million for one !!!!

Para escape.
Yes, the problems of designing a workable and pilot acceptable parachute escape system are absolutely immense .... as was the first problem of getting a rotary wing to fly! Just keep at it. Some of you will know that had such a system been available a few years back, my son may well have survived the in flight break up of a Hughes 300 as would around thirty R22 pilots.

Accidental activation
Will this system be safe if it activates inadvertenly?
Floatation devices have been known to activate in flight! For UAVs it does not matter, I suppose? |
I think the point is that IF it deployed accidentally and the result is a bent helicopter but live pilot ....... You balance that against the ones that could have been saved by in flight failure ....ie nearly all the turbulence related fatalities in Robbos could have been surviveable . A bit like the cirrus system I think this is the biggest development in helicopter safety there could ever be and if it comes out in my lifetime I want one !!!!!! The question is not if it happens but when .
