EH Industries

• Rotary-winged aircraft • Spanish inventor • British manufacture

Juan de la Cierva was born in September 1895. He designed and built a glider when he was 15. and his first three – engined aeroplane in 1918. His true aim was to design an aircraft that would be able to maintain lift, and land safely after an engine failure. Practical helicopters wore impossible with the engines and materials thon available, so he turned to the concept of an aircraft using an unpowered rotor for lift and a conventional propeller for propulsion.

Commercial successes ►

The most commercially successful early design was the C. 19. the first purpose-built autogyro. Twenty-nine wero built.

Air Ministry craft ►

British Air Ministry interest in Cierva’s designs began in the 1920s with tho C.6. Avro was among several Bntish companies ovontually licensed to build autogyros. Tho RAF evaluated several prototypes, including C.6s. a C.8L and C. 19s. In 1934/35. 12 C.30AS were delivered.

FACTS AND

>- Twelve C.30As (designated Rota Mk I) were delivered to the RAF in tho 1930s, followed by 13 civil examples after 1939.

► Among prosorvod Autogyros is a Rota Mk I (C.30A) at the RAF Museum, London.

► British-built C.19s woro sold in countrios like New Zealand, Japan and Australia.

■4 First successes

With subsidies from tho Spanish government, Cierva built the C.6 series, using Avro S04K fusdagci Such was its success that Оспа established a company in the UK

FIGURES

>• During World War II, a Joep was fitted with a rotor and towod behind an aircraft, using the autogyro principle.

► Juan do la Cierva became the first autogyro passenger in a C.60 on 30 July 1927.

► In the late 1920s. Cierva learned to fly his own autogyros.

PROFILE

• Army co-operation • Ambulance/search and rescue • Trainer

Conceived at the end of World War II, the Sycamore was designed by Raoul Hafner and was the first British helicopter to gain a civil certificate of airworthiness. It was used for search-and – rescuo duties and as an air ambulance by tho Royal Air Force, and was also tested by the British Army. The Sycamore was even used by the Federal German army and navy, and British examples saw combat service in Borneo, Cyprus and Malaya.

Bristol Sycamore

Picking up survivors ►

Sycamores pioneered helicopter soarch-and-rescue flights around tho United Kingdom. Most units used the HR. Mk 14 version in this role.

A Evaluation flight

The first Sycamore for Fighter Command. WV781, was flown to St Mawgan by two RAF pilots who had just been trained by Bristol company crows.

A Australian delivery

The aircraft-earner HMAS Vengeance took delivery of the Royal Australian Navy’s first threo Sycamore HC. Mk 51s.

Company colours ►

This Sycamore is flying over tho Severn Estuary not far from tho Bristol factory at Filton. The company gave up helicopter production after tho Belvedere.

FACTS AND

► The rotor blades were constructed of spruce and ply ribs with a plywood covering and a Hydrullgnum spar.

► Originally known as the Type 171, the Sycamore was Bristol’s first helicoptor.

► Tho Sycamore had a simple auto-throttle which the pilot could ovorrido.

FIGURES

>■ Tho last Sycamore version was the HR. Mk 14, which servod with Fighter Command’s No. 275 Squadron.

>• In early Sycamores tho pilot sat to port, but this was later changed to starboard.

► Tho main production version was the Typo 177 Mk 4, which had taller landing gear.

• First RAF twin-rotor • Heavy-lifter • Search and rescue

Bristol’s excellent Belvedere gave new muscle to the Royal Air Force in the 1950s at a time when helicopters were becoming bigger and more versatile. With twin engines and tandem rotors, the slender, cigar­like Belvedere lifted and carried more than any previous RAF helicopter. Never successful in its original purpose as a naval craft, the Belvedere performed well hauling troops, supplies and weapons from land bases.

A Malayan mission

With emergency floats fitted to the side. Belvederes flew search and rescue missions and heavy lift sorties in the junglos of Malaya.

A Flying crane

Due to the lack of roads and the dense tropical /unglo. the Belvedere was used for transporting heavy items in the Far East.

▼ Back to the drawing board

The Type 173 was the initial prototype. On its first flight the tost pilot found it would only fly backwatds

A Naval trials

The Belvedere was initially developed to meet a Fleet Air Arm requirement for a ship-based transport and anti-submanno helicopter, but it was never ordered.

FACTS AND FIGURES

► The first Belvedere suffered noise and stability problems – rectified by rodosigning the rotor hubs and tailplane.

>• On 24 August 1952 the prototypo for the Bolvodcre series made its maiden flight

► The prototype was domonstratod at the Farnborough air show in September 1952.

► British European Airways leased n Bolvodero briefly but never used it in commercial service.

► The first production aircraft with Gazelle engines made Its Initial night in July 1958-

>• The Belvedere had a long career, onding Its RAF servlco in March 1969.

ClERVA

n 1946 the first of Brantly’s helicopter

designs, the over-complex B-1, flew for the first time. Undaunted by the unpopularity of his initial design, Brantly went on to produce the best-selling B-2. Through at least three changes of company ownership, the B-2 remained in constant production, a testimony to the soundness of the basic design. Constant improvements allowed the type to remain in production from 1958 until 1994.

A Attractive presentation

Finished m a bright colour scheme, the Brantly B-2 is an attractive and sleek-hoking helicopter. Several examples remain in regular servico.

Unchanging design у

This early B-2A demonstrates the original lines of the typo and how little they wore fo change dunng three decades of production.

A Army evaluation

Five B-2s were tested by the US Army under the designation YHO-3-BR. No production order resulted from this evaluation and tho B-2 also failed to win orders from the British Army.

▼ In the business

This immaculate B-2B is seen under the ownership of Helicopter International Magazine.

FACTS AND FIGURES

► When Brantly was taken over by Hynes, tho B-2 becamo tho Brantly-Hynes B-2. It continued in production until 1994.

► Brantly also developed the 305, a larger, five-seat helicopter based on tho B-2.

Float, skid or wheeled landing gear was an option on all B-2s.

► James T. Kirnurn was tho third owner of the B-2 type certificate, and delivered he* first B-2B on 25 August 1990,

>• British Executive Air Services acquired a production licence for tho B-2.

> In 1992, a B-2B cost US$120.000 to US$135,000 depending on equipment fit-

◄ Resupply at sea

Transporting stores at sea is tlw UH-46’s mam task, ferrying toads from replenishment ships to warships. HH-46s serve n a similar role, but have a winch for scarch-and-rescuc duties.

▼ Frozen North

In support of US Manno Corps detachments CH-46s arc deployed to Norway. This is especially challenging as crews have to fly over the mountainous terrain m extreme weather

▼ Shot down

This CH-46 was shot down dunng the American intervention m Grenada. One of the weaknesses of the Sea Knight is that it has WOc armour and is vulnerable to small arms fire.

Storm service ►

Tho biggest doptoymont for the CH-46 in recent years was Operation Deserf Storm. Sixty wore used for such varied tasks as casualty evacuation, resupply and vertical replenishment.

FACTS AND FIGURES

► The prototype flow on 22 April 1958, with tho first production CH-46 following on 16 Octobor 1962.

► Tho US Army tostod n version of tho CH-46 but docidod not to operate it.

► In 1965 tho Sea Knight replaced tho Sikorsky H-34 with Marino units in Vietnam.

► Some 669 Sen Knights were built: US Ha’H and Marine Corps models served in Operation Desert Storm.

With the Boeing MH-47E. the US

Army enhanced its ability to carry out secret missions deep in enemy territory at night and in foul weather. The dark, dangerous-looking MH-47E is today’s special operations version of the much – admired Chinook of the Vietnam era. With high-tech terrain-following radar and an infra­red sensor, the MH-47E is the trump card of the US Army’s famous ‘Night Stalkers’.

• Civil CH-47 variant • Oil exploration support • Limited production

epresenting the muscle among the Western world’s helicopter designs, the Chinook was seen as an ideal aircraft for companies specialising in construction, logging and petroleum exploration. Although the Chinook was designed for military use and is well-known for its US Army duty in Vietnam, this big, durable, rotary-wing craft can handle heavy cargoes and travel respectable distances making it ideal for commercial applications.

◄ Dual-role heavy litter

Booing Helicopters marketed the Commercial Chinook as an aircraft combining heavy-lift capabilities (nine tonnes internally or 12.7 tonnes externally) with a useful 44-seat passenger load.

◄ Prototype

The first military CH-47 Chinoob took to the гиг n 1961. tt was not until 19 August 1980 that this, the 234LR prototype, was first flown.
