After a surprisingly decent Victoria Sponge in the cafe, I started to make my way around the museum. This little one caught my eye, adorably called a Skeeter. With a 200-horsepower engine, it had a top speed of around 109 mph/175 kph. Only a few survive, including one at the equally quirky North East Land Sea and Air Museum.
The Westland Whirlwind on the left served in the Royal Navy for 14 years, then sat for 20, and was privately restored to flying condition. The smaller Wasp was a turbine-powered development of the Skeeter you saw earlier.
A Westland Whirlwind, which was a licence-built Sikorsky S-55. This one had an extremely long life. Built in 1955 as a Series 1, it received a new engine and other updates to bring it in line with the current Series 3 in 1965. It continued its service as a training helicopter and for charter services until 1993.
The Westland Dragonfly was a licence-built British version of the Sikorsky S-51, a very early production helicopter. How early? They entered service right after WWII. This example was the 50th Dragonfly built and served the Royal Navy in various roles until 1967.
The pilot sits behind and above the gunner. A modified Hind held the speed record for helicopters from 1978 until the Lynx you saw earlier beat it in 1986. That's even more impressive given how huge and heavy this attack and transport helicopter is.
There is no direct NATO counterpart to the Hind, being an attack helicopter first and foremost, but also able to carry passengers. Helicopters like the Sikorsky UH-60 and its variants can certainly mount significant armament, but weren't designed as attack helicopters per se (they're classified as either utility or assault helicopters). And our attack helicopters can't carry troops. Though the Blackhawk (no space) would have.
This oddity is the dual-engined, coaxial-rotored Cierva CR Twin, also known as the Grasshopper. This is one of three prototypes, and the only one surviving. It never went into production. Each rotor is powered by a 210hp flat-6 engine.
This big fella is a prototype EH101, a joint venture between Westland and Italy's Agusta for a "medium-lift" helicopter. It has three engines, but is able to list off even under full load with one engine disabled.
This is configured as the civilian variant, but there are multiple military versions. EH101s are still in production and in use all over the world.
The German-built MBB Bo 105 is so bland-looking I almost skipped it. Turns out this was the first dual-engined helicopter of its size, and its light weight and high power let some variants do acrobatic maneuvers like loops and rolls. The BMW M3 of the helicopter world, if you will.
A Bell 47, the first helicopter to get a commercial certification, perhaps best known as the helicopter, in military H-13 guise, at the beginning of M*A*S*H. This one, and bear with me here, was built in the UK by Westland, under a license held by Agusta in Italy to produce the American helicopter design, and was given to the UN for use in Cyprus.
I've never seen a Kamov Ka-26 Hoodlum before, and I like it. With a twin-tail, coaxial rotors and those great engine pods, it's got a Thunderbirds vibe to it. You can see the interchangeable pod resting below where it would usually mount. This version carries a few passengers; there were also cargo pods, a chemical hopper for crop-dusting, or simply none to use the Ka-26 as a sky crane.
The Piasecki HUP Retriever is a tandem-rotor design, but interestingly, it only has a single engine. If the name Piasecki doesn't sound familiar, they became Vertol, then Boeing-Vertol, and are responsible for the most iconic tandem-rotor helicopter, the Chinook.
A sleek Eurocopter Dauphin. This example was the first production model of the improved N variant, which came out in 1980. It was used to set speed records between London and Paris. Top speed was 189 mph/305 kph.
This is called a Fenestron, also known as a fantail, one of the features that makes the Dauphin look so slick. Yes, those thin pieces are the blades. A fantail like this offers potential benefits like reduced noise and better performance. It's hard to tell, but the blades are unevenly spaced, to tweak the acoustics of the fan (for the better). Though somewhat common now, this was only the second helicopter to feature one.
The Sud-Ouest Djinn wasn't just an early helicopter, it was also the first mass-production tip-jet rotorcraft. A portion of the turbine's exhaust was routed up through the rotor and out the tips, spinning the blades. No tail rotor was needed since there was no rotational torque on the aircraft.
The legendary Bell UH-1 Iroquois, aka the Huey. Over 30,000 were built. This example had a rather incredible life. It was delivered directly from the factory to Vietnam in 1967 and likely saw use during the Tet Offensive. It then saw service in Europe, and later in Saudi Arabia during the first Gulf War.
OK, last Whirlwind of the tour. You know that big funny nose? That's actually where the engine is, not up near the rotor like most helicopters. In most Whirlwinds it's a radial of somewhere between 7- and 14-cylinders, but in this converted Mk 10 it's a 1050hp turboshaft. That's why its nose is so much bigger, but you were polite enough not to ask.
Probably the largest helicopter at the museum, the Super Frelon. It's got three 1,550hp turboshaft engines for its one rotor, which was designed by Sikorsky. The gearbox was developed by Fiat. It's predominantly a military helicopter, but this a prototype civilian variant that spent two seasons as a shuttle in the Greek islands for Olympic Air when it was owned by Aristotle Onassis. It wasn't profitable.
The Hughes OH-6 you just saw was designed for, and won, the US Army's LOH competition in the early '60s. Bell also entered the competition, and while its design didn't win, the company modified it for civilian use. That helicopter, the JetRanger, is one of the most successful civilian helicopters and one of the most recognizable. The Army even bought a modified version of this design to be the OH-58 Kiowa. This example was licence-built in Italy by Agusta and flew for over 30 years.
This is a Eurocopter Super Puma, modified by Bristow Helicopters for more passenger comfort and safety for use in its long-range oil platform transport business. Bristow called its version the Tiger, and with it the company pioneered the now-standard Health and usage monitoring systems (HUMS) on helicopters to keep track of mechanical wear and potential maintenance issues.
