Description
20mm M39 Operating Compression Spring. P/N 7184232
The 20mm M39 Operating Compression Spring, P/N 7184232, is a steel mechanical spring associated with the operating mechanism of the M39 20 mm aircraft gun. It is also identified by NSN 5360-00-718-4232.
Historical Significance
The M39 was a Cold War-era 20 mm automatic aircraft cannon used on U.S. military aircraft, including the F-100 Super Sabre. Internal components such as the 20mm M39 Operating Compression Spring represent the mechanical parts that supported this generation of aircraft armament.
Parts with documented military and federal stock numbers also help preserve the technical history of how these aircraft gun systems were cataloged and maintained.
What This Item Is and Does
The 20mm M39 Operating Compression Spring is a helical spring designed to shorten under axial load and push back as the load is released. Within the M39 operating mechanism, this spring action stores mechanical energy and supports the movement and return of associated parts.
In the gun’s operating assembly, the spring provides controlled force for repeatable mechanical movement.
