Reusability of Filament-Wound Composite Launch Tubes When Subjected to the Exhaust of Rockets Using Aluminized Propellant.

摘要

It is the intent of this report to initiate the search for material combinations that will permit the repeated use of filament-wound launch tubes with rockets having aluminized propellant. Initial qualitative screening was accomplished, under contract, by the Brunswick Corporation. Further in-house evaluation was performed on tube sections containing selected material combinations resulting from the initial screening process. The use of various material combinations as a basic tube matrix was unproductive. It seems that a liner is essential to the reuse of filament-wound launch tubes. Several liner material combinations for filament-wound tubes are proposed for scaled live-firing tests with motors having aluminized propellant. It is also recommended that qualitative screening be continued for other liner material combinations. (Author)
