Turbo CT over the Alps!

Recommended Posts

Can the turbo 914 and variable propellor be installed into one of the "experimental" CT's or does the 120kt limit still apply?

You can't have a variable or constant speed prop either here in the US and a 914 with a ground adjustable prop is a total waste.

I wouldn't say it is a total waste. For someone like Ed who is flying at higher altitudes all the time the extra power of the turbo would be nice, compared to normally aspirated. Aslo for someone who is doing a lot of cross country flights at higher altitudes it would be helpful as well.

155 KTAS. Isn't TAS ( and not indicated AS ) the airspeed that determines an overspeed with possible flutter and breakup resulting? There is a good article about that on the Van's RV site. I know my CTSW has a 145 KIAS redline so I would assume that I should not exceed 145 KTAS.

Anyway, this is an area of flight in which I have no experience. Maybe some of you high flyers or technophobes could chime in.

There is evidence of higher VNEs for our CTs and the reasons other than chute deployment are not well known.

 

Most limitations have to do with IAS but with flutter you could be at a safe IAS but not TAS so you have to shift your thinking.

I would not even consider a higher Vne in a CT with a full-span anti-servo trim system.  The flutter I encountered was at around 123kt indicated.  Since the factory reinforcement I have taken the airplane close to the 145kt Vne, but I would not push it.

the CTs with the partial-span tabs seem to be immune to the flutter concern at any reasonable speed.

Love to fly in the area Gica passed over and remembering some of the climbing and skiing many of those mountains years back. Nowadays a few more horsepowers for my CTLS would be great when it gets hot. However I have to tell Gica that according to the route he did not pass over Grossglockner (Austria`s highest mountain) . The glaciercapped mountain he saw and crossed from LOIJ was Grossvenediger ,12054ft, he should have made a left turn over Pass Thurn heading for one of two GA crossings of the Alps there . Anyway, it`s a great country to fly in good weather and it gets phantastically rocky towards Cortina d`Ampezzo.

Anselm,

My wife and I drove up to the Kaiser-Franz-Josefs-Hohe (I hope I said that right) under the Grossglockner two years ago. It was a wonderful trip in a beautiful country.

I was in the area at August, 25th. Unfortunately not in a CT but in a Bristell.

This time my sweetpea enjoyed the trip. Mostly she doesn't like to pass the mountains and closes her eyes, when the rocks/clouds/birds/flies come closer:fainting-1344:

Mike,

congratulations, exact spelling! One of the mentioned crossings follows the pass road to or from Zell am See. Did you pass through the Dolomites?
