Chuffing impressive payload and hot/high performance if I recall...

also had a greater weapons fit available to it than the Mi- 24 Hind

You have all missed one that was available and could have been a worldbeater in the sales dept..

Handley Page Herald, already had been redesigned to incorporate a rear ramp, outclassed the Andover in performance on rough ground and didn't need the squatting gear to offload its cargo, sadly lost to us due to the great mans resistance in joining Waste of Space and Government policy because of that.

Why, what would you like to see?

Rotordyne.. What could have been

General characteristics

• Crew: two
• Capacity: 40-48 passengers
• Length: 58 ft 8 in (17.88 m) of fuselage
• Wingspan: 46 ft 6 in (14.17 m) fixed wings
• Height: 22 ft 2 in (6.76 m) to top of rotor pylon
• Wing area: 475 sq ft (44.1 m2) [47]
• Airfoil: NACA 23015[48]
• Empty weight: 22,000 lb (9,979 kg)
• Gross weight: 33,000 lb (14,969 kg)
• Fuel capacity: 7,500 lb (3,402 kg)
• Powerplant: 2 × Napier Eland N.El.7 turboprops, 2,800 shp (2,100 kW) each [49]
• Powerplant: 4 × rotor tip jet , 1,000 lbf (4.4 kN) thrust each [50]
• Main rotor diameter: 90 ft 0 in (27.43 m)
• Main rotor area: 6,362 sq ft (591.0 m2) Rotor aerofoil: NACA 0015
• Blade tip speed: 720 ft/s (219 m/s)
• Disc loading: 6.14 lb/ft2 (30 kg/m2)
• Propellers: 4-bladed, 13 ft (4.0 m) diameter

Performance

• Maximum speed: 190.9 mph (307.2 km/h, 165.9 kn) speed record [51]
• Cruise speed: 185 mph (298 km/h, 161 kn)
• Range: 450 mi (720 km, 390 nmi)
• Service ceiling: 13,000 ft (4,000 m)

The larger Rotodyne Z design could be developed to take 57 to 75 passengers which, when equipped with the Tyne engines (5,250 shp/3,910 kW), would have a projected cruising speed of 200 kn (370 km/h). It would be able to carry nearly 8 tons (7 tonnes) of freight; cargoes could have included some British Army vehicles and even the intact fuselage of some fighter aircraft that would fit into its fuselage.[30] It would have also been able to carry large cargoes externally as an aerial crane, including vehicles and whole aircraft. According to some of the later proposals, the Rotodyne Z would have had a gross weight of 58,500 lb, an extended rotor diameter of 109 ft, and a tapered wing with a span of 75 ft.[31]

NutLoose, thank you so much for making public the Rotodyne / Chinook comparison (one which I had considered privately in the wayback).
What an opportunity lost ... one of so many in that era.

The noise issue had been sorted apparently when it was canned. Imagine what we would have today with development.

Nor the RAAF for that matter...

I know some people at Fairey's - that's not what they say - there were "hopes" they could reduce the noise but development was stopped before they could really show it was acceptable..... and acceptable in the '60's is very very different from acceptable today - there were still a load of Caravelles flying around Europe then

Hanger? Don't you mean standard tropical island?

[FantomZorbin]

I understand that a Rotodyne landed at Fairey's in what had been a coalyard adjacent to the factory in Hayes Middx … is this true?

but as said, old technology, for one engines today are a lot quieter than the almost straight turbojets of the period, nothing that cannot be fixed, and we are talking military, the likes of the Typhoon / Harrier sn't exactly quiet.

Ahhh the Caravelle, a Comet in disguise, . I take it you know why..
