Unearthed - the 2nd known photo of the cessna "coax" prototype!
built and flown sometime in 1986-1987, this aircraft started life as a standard, run-of-the-mill cessna 340 twin.
cessna engineers removed the two wing-mounted 310hp piston engines and replaced them with two allison 250-c20s turboprops rated at 375 shp.
the two new turbine engines were joined via a common gearbox and coaxial output shaft, driving two three-bladed propellers which turned in opposite directions.
now sporting centerline t****t and turbine reliability, the new aircraft (unofficially named "coax") should theoretically have provided much-improved safety and reliability over the original 340 had it entered production.
and it likely would have performed better, as it reportedly outclimbed the ‪340a‬ by 200 feet per minute in both single and multi-engine climb rates.
it’s so frustrating to think that there’s a room somewhere packed with fascinating historical photos of cessna history, forever sealed and hidden from public view.
any chance one of you fine avgeeks have a connection at cessna or textron who might allow me access to that room so that i could document and share my findings? ⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ ⠀ ⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀ #avgeek #aircraft #aviation #pilot #avpic #avpics #instaplane #instapilot #instaaviation #flight #flying #plane #planes #airplane #instagramaviation #aircraftrecognition #cessnateur #aircraftmaintenance #aviationmaintenance #turboprop #twincessna #cessna #cessna340
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

I first encountered an OMA SUD Skycar at Oshkosh several years ago. 
At that time, I was mostly focused on the unusual design of the thing.
The sleek forward fuselage, pusher configuration, twin tails, and unique rear cargo door broke new ground, and made it stand out among all the other light twins. 
What I didn’t realize at the time was just how underpowered the thing is. 
The two Lycoming IO-360s produce 200hp per side, but they’re tasked with keeping 4,400 lb (1,995 kg) in the air. 
This provides the Skycar with an even worse power-to-weight ratio than the Piper Seminole, which itself is certainly no rocket. 
I wonder whether this was a factor in the crash of the first Skycar that occurred in Egypt when it “impacted desert sand” while on approach to Hurghada Airport. 
Regardless, it’s darn cool-looking, and I hope the company succeeds if only to introduce a new, unique element to the general aviation fleet. ⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ ⠀ ⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀ #avgeek #aircraft #aviation #pilot #avpic #avpics #instaplane #instapilot #instaaviation #flight #flying #plane #planes #airplane #instagramaviation #aircraftrecognition #cessnateur #aopa #eaa #omasud

Before take off check list. Делайте звук 🔊
И сможете наслаждаться голосом пилотов в кабине перед взлётом 😏
👨🏻‍✈️ Перед взлетом пилоты проводят проверку готовности к взлету. Для этого у них есть список и по нему происходит двойная проверка.
👨🏻‍✈️ Обычно командир начинает, а второй пилот подхватывает. Но может быть и наоборот. Идёт двойная обратная связь.
👨🏻‍✈️ Помните, я писала про вкладыш в пилотское? Я говорила о том, что практически все в работе пилота дублируется. От приборов в самолёте, до документов и двойной обратной связи.
👨🏻‍✈️ Дублирование необходимо для безопасности полёта. Если была ошибка, на повторе ее заметят.
👨🏻‍✈️ Проверяется готовность самолёта и рассчитываются скорости. Их три. Об этом расскажу в следующий раз 😉
