Rated boost was plus 2 lb, and weight 1,177 lb.Įarly bench tests resulted in persistent cracking of cylinder jackets and failures of the double-helical reduction gear. When the first example was run on October 15th, a number of weaknesses were revealed, and it was not until July 1934 that a 100-hr type-test could be completed.
Consequently, work was started on a new 1,100 hp (820 kW)-class design known as the PV-12, with PV standing for Private Venture, 12-cylinder, as the company received no government funding for work on the project.ĭrawings for the P.V.12 engine, as the Merlin was originally called, were begun in January 1933. We’re grateful to Google Arts & Culture for preserving the company’s involvement in its efforts to keep American airmen safe.Rolls-Royce started planning its future aero engine development programme and realised there was a need for an engine larger than their 21-litre (1,296 cu in) Kestrel which was being used with great success in a number of 1930s aircraft. During the 1940s, this was a high calling indeed. It also helped to create well-functioning, reliable aircrafts to aid in the war effort. These images remind us that Packard not only made people’s lives easier through high-quality luxury vehicles. After leaving LIFE Magazine in 1951, Hoffman developed Bernard Hoffman Laboratories to focus on making improvements to professional photographic technology. Notably, Hoffman became the first American photographer to capture the aftermath of the atomic bombs dropped on Japan in 1945. Mayer discovered “a couple exterior shots of the new buildings that Packard built at the plant site,” which were specifically designed for use in facilitating the engines’ construction.ĭ ocumentary photographer Bernard Hoffman took these images in 1941. Including nearly two hundred images, these photographs depict the manufacture of the Rolls-Royce Merlin aircraft engines. This second photo collection unearthed by PPG volunteer Richard Mayer is an impressive reminder that the Packard Motor Car Company assisted in the manufacture of aircraft engines during the 1940s.
