Rolls-royce Heritage Trust – Allison Branch

Rolls-Royce Heritage Trust – Allison Branch

The Rolls-Royce Heritage Trust Allison Branch sits on Indianapolis’s west side, and its story starts with a name most racing fans already know — James Allison, one of the co-founders of the Indianapolis Motor Speedway.

From the Indy 500 to Aircraft Engines

James Allison grew up in Indianapolis, working first in his father’s coupon business before starting his own venture making fountain pens. In 1909, he helped found the Indianapolis Motor Speedway, home of the legendary Indy 500. From there, Allison’s engineering ambitions turned skyward, and his involvement in aircraft engines traces all the way back to World War I.

That work grew into the Allison Engine Company, a business that would go on to produce some of the most significant aircraft engines of the 20th century, spanning military and commercial aviation alike. In 1995, Rolls-Royce acquired Allison Engine, though the separate Indianapolis-based transmission company of the same name remains its own entity to this day.

A Museum Built to Preserve That Legacy

The Rolls-Royce Heritage Trust Allison Branch, also known as the James A. Allison Exhibition Center, is dedicated to preserving and promoting the combined history of Allison and Rolls-Royce in Indianapolis. The exhibition spans over 25 aircraft engines and large-scale aircraft models, representing a full century of engineering advancement, from early piston engines like the Liberty and V-1710 through modern turbine and hybrid-electric propulsion technology.

Beyond the engines on display, the Trust maintains an extensive archive of design records and visual media, including more than 16,000 detailed photographs documenting Allison and Rolls-Royce products across defense, civil aircraft, NASA and military space applications, marine, and energy uses.

A Hands-On Experience for Visitors

The museum operates as a 501(c)(3) educational nonprofit, and tours are available by reservation only, typically conducted on weekday mornings with Thursdays preferred. Visitors consistently point to the hands-on nature of the exhibits — actual jet engines, hovercraft motors, and helicopter engines that guests can see up close and, in many cases, interact with directly.

For a city better known nationally for auto racing than aviation, the Allison Branch tells a quieter but equally significant story: that the same Indianapolis ingenuity behind the Speedway also helped power some of history’s most important aircraft.
