So It actually kind of is the case of pulling the T handle and jumping. I am willing to bet my life on it.įor a cool video on a BUFF with the rudder torn off see bellow. Rudder damage to a small aircraft can result in a flyable airplane. This would only happen if the horizontal stab or empennage was torn of from said impact. It appears a lot of folks associate damage to the rudder with uncontrolled pitch down. Without the canopy and canopy forward and side frame, a large part of your body in the RV14 is above remaining airplane structure, and you have a high chance of being thrown from a wildly out of control aircraft vs stuck in it. If one is tumbling it just might change the tumble but keep going. Once uncontrolled having the tail hit or not will probably not add much more to the situation.
#CANOPY JETTISON HOW TO#
If one is in a situation where they are having to bail out, chances are its from severe damage or uncontained fire and knowing how to “properly” fly the airplane in unusual attitudes will not help if the airplane is uncontrollable. They would depart the aircraft almost as if in ejection seats ending up above the aircraft. WWII German pilots used to trim nose down to facilitate bailing out. Will the airplane pitch down if the whole canopy departs? Not sure but a certain amount of downward pitch moment might help to clear the tail from the aft and upward moving canopy. This demonstrates the strength of the upward pull on the canopy. This nose down pitch has been reported as pretty strong. The associated pitch down that folks have reported with tip up canopy inflight opening I believe is a result of the change in aerodynamics from the canopy in effect either pushing the nose down on the hinge or changing airflow over the horizontal tail. I believe this should get it above the tail. Between the negative pressure above and the positive pressure created by catching air the canopy should have a pretty good upward vector with an associated aft tumble. The Aft locking pins would pull out of the holes as the canopy pivoted up. The front of the canopy would now catch air and create even more of an upward and aft tumble of the canopy. This would keep the aft part of the canopy from initially moving up during the jettison process resulting in the front of the canopy being pulled up by negative pressure. The Canopy is held in place to the roll bar by the aft locking pins. Once this happens the big question is will it catch air in the front and tumble rearward or something else. It is safe to assume that if there were no pin holding the front of the canopy down, the whole canopy would get sucked up by the same physics. It is very hard if not impossible to close once opened. If you look at the enclosed pictures when the pins are pulled inboard by the release mechanism the canopy hinge will be able to move straight up out of its slot.įrom previous articles on tip up canopy accidental inflight openings the aft part of the canopy moves up from the negative pressure above it, think top of a wing.
GASMAN I think you are misinformed on the RV 14 canopy release.
