Shar2 Posted March 22, 2016 Share Posted March 22, 2016 Don't see why not, but they'd be a blighter to fold. 2 Link to comment Share on other sites More sharing options...
paul_c Posted March 22, 2016 Share Posted March 22, 2016 I wouldn't fancy doing the tracking and adjustments on them! And the resulting wire locking session would ruin your shift........ 3 Link to comment Share on other sites More sharing options...
Aeronut Posted March 22, 2016 Share Posted March 22, 2016 Mil 26 has eight blades. What are you trying to lift? and don't forget you'll need a fair bit of power for 9 Link to comment Share on other sites More sharing options...
huvut76g7gbbui7 Posted March 23, 2016 Share Posted March 23, 2016 Intriguing! Are you going to do a major modification to the fuselage ? Link to comment Share on other sites More sharing options...
Abandoned Project Posted March 23, 2016 Author Share Posted March 23, 2016 (edited) Have no fear Aeronut! Here is a brief backstory... During talks between AugustaWiffland and the Indian Airforce as to the sale of VVIP Merlins, they were asked if there was any plans for something bigger as the Mil Mi-26's weren't getting any younger and with the production line at Mil busy working on existing orders and the Mi-46 project currently stalled they were looking for an alternative. This got AugustaWiffland considering the chance to improve the external payload capacity if they reworked the engines, gearbox and rotor. So after a couple of days RR were able to commit to the project with a new engine, the RR6K, built under licence by the japanese firm Istabitsa and with the designers working on weight distibution it was found that on paper the following figures were achieved; Empty Weight : 12600kg MTOW : 32560kg And all inside the current footprint of a standard AW101! but with a slight loss of internal payload space due to internal strengthening of the whole structure.... So now I shall start feeding my merlin kit some serious steriods! Edited March 23, 2016 by dadofthree 2 Link to comment Share on other sites More sharing options...
paul_c Posted March 23, 2016 Share Posted March 23, 2016 Flippin' 'eck! Now that's a Mer-dog with real muscle! Looking forward to this. 1 Link to comment Share on other sites More sharing options...
Rob G Posted March 24, 2016 Share Posted March 24, 2016 Hmm... it'll look the dog's proverbials, but I'd imagine that there'd be some serious vortex/wake issues, and probably blades operating in either disturbed air or no air at all. The big Mil may have 8 blades, but it also has a stonking big rotor. Even the CH-53E Super Stallion only has 6 blades. Chinooks only have 3 per end... But then, it's a WHIF, so anything goes. Edit: Big lol at Itsabitsa. 1 Link to comment Share on other sites More sharing options...
Abandoned Project Posted March 24, 2016 Author Share Posted March 24, 2016 Those are good points Rob and I'm sure Sikorsky overcame them when they decided to add an extra blade and a third engine to make the CH-53E Super Stallion out of the 6 blade/2 engine Sea Stallion. Having questioned AugustaWiffland on the subject they're happy with their solution of slowing the rotor speed down by 5rpm as they found the original speed created more vibration and noise than expected. Although this means a loss in lift the MTOW is still acceptable as they new achieving the same characteristics as a Mi-26 was never going to happen. At the end of the day they main goal has been to increase external payload. Link to comment Share on other sites More sharing options...
moaning dolphin Posted March 24, 2016 Share Posted March 24, 2016 Hope it won't have Naval connotations, as I would hate to be the engineer tasked with designing the blade fold system! Bob 2 Link to comment Share on other sites More sharing options...

Aeronut Posted March 28, 2016 Share Posted March 28, 2016 AugustaWiffliand are calling this the AW191 Kite (apparently there was a typo in admin!) Wouldn't be the first time they've had a typo, afterall the EH 101 was meant to be the EHI 01. I'm surprised the typist kept their job long enough to make this second mistake.

Abandoned Project Posted December 20, 2016 Author Share Posted December 20, 2016 I finally got do some modelling since my last post so decided on some kit bashing for the new taller tail. Â 1 Link to comment Share on other sites More sharing options...
Abandoned Project Posted December 26, 2016 Author Share Posted December 26, 2016 Having spent some time working on the rotorhead this morning with the dimensions coming out at around 50-60mm before the blades went on I am calling this a Whif too far.........for now. But the tail is going to be used for my AEW Peregrine 'happy accident ' Link to comment Share on other sites More sharing options...
Abandoned Project Posted December 28, 2016 Author Share Posted December 28, 2016 Please ignore my previous post. IÂ feel I cant give up on this as the Whif machine is stuck in overdrive despite exploding the other day. Oh, and the tail will not be going on my AW161 Peregrine AEW. All I can say is that I'm in for the long haul with this so will be seeking a lot of advice as I build an almost scratch helicopter! Link to comment Share on other sites More sharing options...

Abandoned Project Posted January 2, 2017 Author Share Posted January 2, 2017 Some progress shots from AugustaWiffland as the wreckage of the prototype Kite is being recycled to build the second prototype. Having salvaged the tail end it has been used to create a 30mm extension of the rear frame. Here the Peregrine fuselage is kindly modelling the tail extension. 2 Link to comment Share on other sites More sharing options...
