I wonder when the T629 will make its first flight? Before the T929 or after?
So absolutely no engine from the TV3-117 series?VK-2500
Initial T929 engines are going to be Ukrainian MotorSich made. 14 engines have been ordered. Which means at least 6 prototypes. But as the number is limited to 14 engines, we must be quite confident about the emergence TS3000 turbo shafts in time for serial production.

Better to develop local TS meanwhile, I can't really expect to rely on Ukraine which anytime may turn towards the west and join the herd of embargoers.Take into consideration that 10-ton utility helicopter which will be based on the powertrain of T929 may also emerge soon aswell.
I have a problem with the tail rotor,it looks weak and fragile.

Why dont they use a Fenestron(fantail)?
@Cabatli_53 @Test7 @Spook @TheInsider @Yasar @Anmdt and others.
The only significant drawback to ducted fans like the Fenestron is that the shroud adds weight that offsets at least some of the improvements in performance. Regardless of the weight penalty, noise reduction was one of the primary reasons a ducted fan system was adopted for the now-cancelled RAH-66 Comanche stealth helicopter pictured above. Since the majority of the noise generated by a helicopter tends to come from the tail rotor, designers adopted a ducted fan to reduce noise levels and make the helicopter more difficult to detect. This rotor system was essentially a copy of the French Fenestron yet was referred to by the name Fantail in the US. |
Im sure they can design something similar with lesser weight.It has a French patent and is heavier.
