TR Attack & Utility Helicopter Programs

if it was TS1400 we would certainly know about it by now.

But if it's CTS 800 it should already been tested as they delivered to Gendarmerie.

I think TAI's concern is mainly the helicopter and its performance under the adverse conditions as the engine(CTS800) is more mature in its development.

With which engine? CTS 800 or TS-1400?

I'm 90% sure it's the CTS800. But, it is possible it's with the TS1400 as well, it should be undergoing its tests right about now. It is possible that this test in Sweden and not Turkey was part of both helicopter's and the engine's type certificate tests. They continue to drip feed info on such public matters. It's a civilian helicopter...

Did they deliver the previous helicopters without cold weather tests?

Gendarme helicopters had snow tests last march.

According to the information I have received, over 1,000 hours have been flown during the flight test campaign, and over 100 hours have been flown with the J6001 alone. In this context, the J6001 was also subjected to 'snow tests' in Erzurum last March.

Ah, civilian certificate. I didn't think of that. Now this makes sense.

Not clear if it's the case, but it is the one that makes most sense, with or without TS1400. It's all guesswork save for some scant reporting, as TAI still fails to share milestones clearly.

Everybody at this stage knows my love of T625. But you can't beat bigger size, bigger capacity.

A small container ship faced heavy seas and ran aground on in eastern Canada the other day with a possible danger of ship breaking apart.

2 CH-149 Cormorants, which is the RCAF SAR variant of the AW101 Merlin, were dispatched to help. Per reports, a single Cormorant rescued all 20 sailors on the ship by itself. We have a great video showing the action both from ground and from inside the helicopter.

Coast Guard needs such capable aircraft, as well as the navy and army. Blackhawks are not large enough and we only have 10 Chinooks. I was actually happy that T925 was a 11-12 ton helicopter but latest released designs show a smaller design, basically same size as our S70s. So T925 won't help us for this need. We either need to start another program, or buy from abroad.

GÖKBEY helikopteri test için neden Erzurum’a değil de İsveç’e gitti?

Geçtiğimiz gün Türk Havacılık ve Uzay Sanayi (TUSAŞ) T625 GÖKBEY helikopterinin önemli bir testi daha tamamladığını açıkladı. GÖKBEY yaklaşık 1 ay boyunca dünyanın en soğuk iklimlerinden biri olan İsveç’in Kiruna şehrinde uçtu. Peki GÖKBEY neden Türkiye’nin en soğuk bölgelerinden biri olan...

Gökbey, was subjected to winter tests before in Erzurum. But in Erzurum and Ardahan average temperatures this time of the year is -9 to -11 degrees Celsius. Kiruna Sweden has a -30 degrees average temperature.
To start a helicopter that has stood idle overnight under extreme cold then fly it at those temperatures is the real achievement. Also Kiruna is at sea level altitude. One of the prerequisites of these cold weather tests is to fly at sea level at such cold conditions.

Gokbey flew at 20000ft before.
At best, the temperature at that altitude is -24 degrees Celsius or even colder. But there are other parameters a helicopter has to be subjected to for EASA certification. With Swedish tests these parameter requirements have been met.
