The Westland 30 is a British medium helicopter based on the Westland Lynx. Although Westland foresaw a market for the type in VIP, passenger and cargo transport, and off-shore support operations, production remained limited, ending in 1988 after only 19 had been sold.

Design and development

In the 1960s Westland was looking for a replacement for the Westland Wessex and Westland Whirlwind helicopters which were then in service with civil and military operators. Westland considered a civil version of the Westland Lynx initially but then turned to a design that was larger but still used many of the components of the Lynx. Although outwardly similar in shape to the Lynx and using the same transmission and rotor blade structure (although a larger slower turning 4-blade rotor) the fuselage is larger and entirely new. The fuselage is a conventionally built structure of aluminium while composites are used for the tail boom.

As a civilian carrier, fitted with airstair or sliding doors it can carry up to 22 passengers with a baggage compartment at the rear of the fuselage.

Fitted for offshore work the Westland 30-100 could operate with a 250 km radius of action (227 kg fuel) carrying nine passengers out and 13 home. As a military aircraft it can carry 14 troops with equipment, 17 without or six stretchers and medical attendants.

The prototype of made its first flight on 10 April 1979 and made an appearance at the Paris Air Show the same year. Production and delivery of the first model, the W30-100, began in 1981. This was followed by the W30-160 with more powerful (940 kW) Gem 60 engines.
