Developed from Westland Lynx

The Westland 30 is a medium-sized civil helicopter designed and produced by the British aerospace company Westland Helicopters. It was derived from the Westland Lynx series of military helicopters, with which it retains a high level of commonality.

Contents

The Westland 30 was developed during the late 1970s and early 1980s primarily as a foray into the civilian market. The company sought to expand its presence in that sector, leveraging its existing portfolio to do so; the Lynx shared its dynamic system and other components with the Westland 30, but the latter featured an original airframe to accommodate a sizable passenger compartment. Westland believed that the Westland 30 could be an attractive to operators of air ferry and offshore drilling flights; it was also intended for use as in a military capacity akin to the Aérospatiale SA 330 Puma. It was initially self-financed by the company, although support from the British government was later forthcoming. It had been estimated that there was a worldwide market for around 400 Westland 30s.

On 10 April 1979, the prototype WG30 made its maiden flight. Civil certification from both the Civil Aviation Authority (CAA) and the Federal Aviation Administration (FAA) soon followed. While no military customers would be secured, civilian operators included British Airways Helicopters, Airspur Helicopters Inc. and Omniflight Helicopter Services. The most prominent operator was the Indian company Pawan Hans; the company acquired 21 Westland 30s for oil exploration purposes; however, the type proved difficult to operate in the tropical climate and two fatal accidents occurred, leading to Pawan Hans' fleet being grounded in 1991. India's use of the Westland 30 became a controversial and politically-changed matter for a time. No major operations of the type has since occurred, and the CAA had withdrawn its license by 2000. [2]

Design and development

During the 1970s, several figures at Westland Helicopters, which had a traditionally military-orientated product line, were keen to develop its range to better cater for the civilian sector as well. It had recently completed development of the Lynx, a fast and agile helicopter that was designed for military operators; yet, it had been decided that pursuing civil certification of the Lynx itself was not a financially prudent move, largely due to the limited appeal that it was thought to have to civil operators. [1] At the same time, the company was investigating replacements for its Wessex and Whirlwind helicopters. It was identified that an enlarged version of the Lynx could suit market requirements in addition to the sought successor role. [1]

Accordingly, Westland opted to conduct a detailed study into the civilian-orientated large Lynx concept; it was originally designated WG-30 Super Lynx, but subsequently received the designation Westland 30. [1] [3] This rotorcraft shared the dynamic components, such as the transmission and composite rotor blades, with the Lynx, along with various other commonalities; it primarily differed by its adoption of a new airframe. [4] It featured a conventionally constructed structure composed of aluminium, some elements, such as the tail boom, used composite materials. [4] While mostly identical to that of the Lynx, the rotor system of the Westland 30 is somewhat larger, thus the four blade main rotor assembly turned at a reduced speed to compensate. [4] It was powered by a pair of Rolls-Royce Gem 60-3 turboshaft engines, capable of generating up to 1260 shp;. [1]

The Westland 30 was primarily designed to function as a civilian helicopter; in a passenger carrier capacity, it could carry up to 22 passengers. [4] [1] Entry to the passenger compartment was via sliding doors on the side of the fuselage, an airstair could also be used; there was a separate compartment for stowing baggage located at the rear of the fuselage. In an offshore configuration, the Westland 30-100 could operate with a 250 km (130 nmi) radius of action (227 kg fuel), carrying nine passengers out and 13 home. [4] Furthermore, Westland designed the WG.30 so that it could undertake air ambulance and tactical transport military missions. In a military capacity, the Westland 30 could carry a maximum of 14 troops along with their equipment, up to 17 without, or up to six stretchers and accompanying medical attendants. [4]

Westland decided to proceed with full-rate development, despite an initial lack of government financing for the project; instead, the Westland 30 was self-funded by the company. [1] In the military sector, it would compete with medium-sized rotorcraft such as the French-built Aérospatiale SA 330 Puma. According to the aviation author Stanley McGowen, Westland was counting on the receipt of orders from civil operators that would use the Westland 30 in roles such as an air shuttle, transferring passengers between airports and city centers. [1] By 1981, the Westland 30 was promoted as having a potential global market for 400 rotorcraft. [5] Ultimately, the British government would provide funding to support the programme. [2]

On 10 April 1979, the prototype WG30 conducted its maiden flight. [6] Later that same year, it was put on public display at the Paris Air Show. [4] During 1981, production of the first model, the Westland 30-100, commenced. The type received type certification from the British Civil Aviation Authority (CAA) during December 1981; American Federal Aviation Administration (FAA) certification followed in December 1982. [6] Development of the type continued beyond the Westland 30-100; in 1983, the 30-200, powered by a pair of General Electric CT7-2B turboshaft engines, made its first flight, [7] and the 30-160, which was outfitted with uprated Gem engines, was first flown in 1984. [7] Further models were proposed. However, production of the type was discontinued in 1988, Westland themselves concluding it to have been a commercial disappointment. [1] [2]

Operational history

On 6 January 1982, the first of three Westland 30-100s was delivered to British Airways Helicopters at Beccles; it was put to work supporting gas rigs in the southern sector of the North Sea. The type was later used on the scheduled passenger service between Penzance and the Isles of Scilly, and remained in service when the company became British International Helicopters during 1986. [8] There was a reported reluctance within the CAA and the British Airports Authority to permit a helicopter service linking Milton Keynes with London City Airport. [5]

In the United States, Airspur Helicopters Inc. acquired four Westland 30s on lease to operate scheduled passenger flights in the Los Angeles area, beginning on 9 May 1983. [9] Omniflight Helicopter Services also operated the type on be ehalf of Pan American World Airways, linking John F. Kennedy International Airport with Pan Am's heliport at East 60th Street in central Manhattan. [1] Services ceased on 1 February 1988, [10] and the helicopters were returned to Westland; the majority of these would eventually be donated to The Helicopter Museum in Weston-Super-Mare.

The chief operator of the type was the Indian company Pawan Hans. During March 1986, the British government agreed with India to supply 21 Westland 30s for oil exploration duties using a British grant of 65 million pounds. [11] India was allegedly reluctant to accept the deal until it was made clear that the aid would not otherwise be forthcoming. [3] [12] Between 1986 and 1988, the rotorcraft were delivered to Pawan Hans for offshore operations on behalf of the Oil and Natural Gas Corporation Limited (ONGC). A similar number of Aérospatiale SA 365N Dauphin helicopters was also supplied by France. It was soon found that the Westland helicopters were ill-suited to Indian conditions, issues with the Gem engines were reported along with high servicing requirements. [1] [2]

In the aftermath of a pair of fatal accidents, Pawan Hans' fleet of Westland 30s was grounded and placed into storage in 1991; various proposals for their fate were examined throughout the 1990s. [13] During October 2000, 19 of the surviving helicopters were sold to the British company AES Aerospace, but after six had been shipped to the United Kingdom, the deal fell through. It is believed that the rotorcraft are in storage at locations in both the United Kingdom and India. [2] [3]
