Re: [c-a] VE/LE rollover structure


Along that line of thought, I actually flew my defiant for a few years with cables in racing tradition, that prevented an engine from completely departing an aircraft making the balance impossible. The engine mount could fail but the weight of the engine would not depart the airframe. True story. I also had tubes I could flood the engine compartment with halon in case of a front or rear engine fire. You can add to the list ballistic parachute, air bags. Some of these never got acted on fortunately. N27ez. Motored on for me for 1700 hours thru some very interesting flights, and a few serious dangers. Defiant Delivered

Interesting video.

One might reflect that in such racing, it's not if an accident will

happen, it's when.  One might also hope that flying and EZs is a bit

less risky.

Regardless, it's still a question of when, not if, for flying also.

Proof is, it's already happened, more than once.

I would not advocate the same structure in an aircraft.  One reason is

that in a race, crash equipment is there, and ready to roll, right now.

No crash equipment when someone goes down in a corn field.  People need

to exit a crashed aircraft, ASAP.

I'd also suggest that existing canard aircraft will not be getting a

rebuild with autoclaved carbon fiber.

Could a new design have much better designed in crash protection?  I'm

pretty sure it could.  Maybe such will happen, someday.

Always good to consider new ideas.
