دانلود کتاب Unified computer model for predicting thermochemical erosion in gun barrels

توضیحاتی در مورد کتاب به زبان اصلی :

Watervliet, New York: US Army Benet Laboratories. 1995The first known gun barrel thermochemical erosion modeling code is presented. Ibis modeling code provides the necessary missing element needed for developing a generalized gun barrel erosion modeling code that can provide analysis and design information that is unattainable by experiment alone. At the current stage of code development, single-shot comparisons can be made of either the same gun wall material for different rounds or different gun wall materials for the same round. This complex computer analysis is based on rigorous scientific thermochemical erosion сonsiderations that have been validated in the reentry nosetip and rocket nozzle community over the last forty years. The 155-mm M203 Unicannon system example is used to illustrate the five module analyses for chromium and gun steel wall materials for the same round.
