Tactile Engine Prototype
NATIONAL AIR AND SPACE MUSEUM
SCOPE OF WORK
The National Air and Space Museum (NASM) was awarded a grant from the Smithsonian
Accessibility Innovations Fund (SAIF) to create an accessible prototype of a hands-on engine
interactive in preparation for NASM’s upcoming Nation of Speed exhibition. The goal of the
interactive is to help visitors understand how engines generate speed and how they can be
modified to go faster. SIE worked with NASM to develop, design, produce, and program the
prototype, which was based on a Ford Flathead V-8 engine. The result was a multi-sensory
experience incorporating tactile components, audio, and lights.

The prototype interactive was modeled after a Ford Flathead V-8 Engine.

Molding the Engine Parts: The engine prototype requires both stock and perfomance parts.
SIE used a foam model of the Ford Flathead V-8 Engine to model some of the prototype components. (above)
SIE purchased real performance parts and cast rubber molds to create prototype parts, such as the performance cylinder heads. Molding prep (above), foam molds and resin cast prototype parts (below).
Using the molds we made from the performance parts, SIE cast the parts in urethane foam, added magnets and locating pins, then painted the casts for durability.

Electronic Interactive Components
The LEDs, speakers, and touch-activated vibrators are all controlled by an Arduino microcontroller. (left)
SIE prototyped the electrical light, sound, and vibration components with an evolving circuit layout. SIE made clear casts of spark plugs and incorporated red and white LEDS. (center and right)
