History

Range S-3 was originally developed for use in aircraft canopy testing. The gun validated many of the canopies designs used on fighter aircraft over the last several decades. The range also played an instrumental role in developing the ASTM F330 specification: Standard Test Method for Bird Impact Testing of Aerospace Transparent Enclosures.

Capabilities

The gun uses a large compressed air reservoir to launch a projectile out of a 7 inches (177.8 mm) diameter barrel. Launch speeds of 200 to 1400 ft/s (61 to 426.7 m/s) can be attained . The barrel can also be reconfigured to launch square or rectangle projectiles. The most commonly used projectile is a dead chicken prepared in accordance with the ASTM specification.
