Sometimes, rare aircraft are destroyed to help improve aviation safety.
and apparently, some of these aircraft mysteriously return from the dead.
here, we see a learavia lear fan 2100 that has undergone impact testing by nasa.
a total of three lear fans were built during the early 1980s, and it was an unusual aircraft, indeed.
sporting a fully composite fuselage and a single pusher propeller driven by two pt-6 turbine engines via two independent driveshafts, the lear fan aimed to provide easy single-engine handling characteristics while also providing multi-engine reliability.
the faa, however, was skeptical about the reliability of the gearbox.
they refused to issue an airworthiness certificate, dooming the project.
in this test, the aircraft was raised to a height of over 150 feet, and then swung from cables, pendulum-style, into a barricade.
just before impact, pyro-technic devices released the suspension cables from the aircraft to allow free flight, and it impacted the barricade at about 60 mph.
the intent was to test an energy absorbing sub-floor and seats, and also to develop a more accurate computer model to predict composite aircraft crashworthiness.
here's the part i can't figure out - this test took place in late 1999...but today, all three aircraft are accounted for, on display and seemingly intact at various facilities.
so which of the three was used for the impact test? and who repaired it (and to what extent was it repaired) before placing it on display? ⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ ⠀ ⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀ #avgeek #aircraft #aviation #pilot #avpic #avpics #instaplane #instapilot #instaaviation #flight #flying #plane #planes #airplane #instagramaviation #aircraftrecognition #cessnateur #pt6 #pt6nation #aopa #eaa #nasa #engineering #airsafety
