In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a specialist in landing gear and hydraulics.
In 1958, Bristol Aeroplane and Rolls-Royce agreed to sell Rotol and British Messier to the Dowty Group.] By 1959 Rotol and British Messier along with Dowty Equipment and Dowty Fuel Systems became part of the new Dowty Aviation Division based at Cheltenham.

Following a series of changes of ownership, the original Dowty Rotol facility at Staverton is now owned by the Safran Group, operating as part of its Messier-Bugatti-Dowty Landing Gear subsidiary. Propeller design and manufacture was moved a few hundred metres down the road when the company was split into business units under its Dowty ownership in the early 1990s. On 16 January 2007, Dowty Propellers became part of GE Aviation Systems through GE buying Smiths Group

On 5 February 2015, a fire at Dowty's Staverton facility caused severe damage to 80% of the factory building, destroying the main production line. A facility at Vantage Point Business Village in Mitcheldean, Gloucestershire, was selected for the company's interim propeller blade manufacturing. In late 2019, the company began moving its operations to an all-new purpose-built facility at Gloucester Business Park in Brockworth, on part of the site of the former aerodrome used by the Gloster Aircraft Company.
