High altitude rail-gun launch systems are constrained by severe aerodynamic heating and power demands
Hypersonic electromagnetic railgun systems face extreme aerodynamic heating and complex flow-field conditions during high-altitude launches, requiring specialized thermal and structural management.
The claim specifically asserts that high-altitude rail-gun launch systems are constrained by severe aerodynamic heating and power/thermal demands. Paper [4] directly evaluates the aerodynamic heating, heat flux, and thermal environment of a hypersonic electromagnetic railgun projectile across various altitudes. Paper [9] examines the extreme initial velocity and aerodynamic forces involved in railgun projectile separation. Thus, the available evidence supports the claim.
