Abstract How successful are sanctions at targeting the economic interests of political elites in affected countries? We study case Iran, using information on stock exchange-listed assets two specific entities with significant influence over direction Iran’s nuclear programme. Our identification strategy focuses process negotiations for removal, examining which benefit most from news about diplo...

The waverider is widely used in hypersonic vehicles with its high aerodynamic performance, but due to the serious aerothermal environment, sharp leading edge should be blunted. Circular blunt one of commonly characteristic protection methods. larger diameter can reduce peak heat flux, at same time, it will lead drag. existing research shows that under two-dimensions, non-uniform flux by 20%, an...

A computational study was performed to explore the aerodynamic performance of a streamline-traced, externalcompression inlet designed for Mach 1.664 at off-design conditions of freestream Mach number, angle-of-attack, and angle-of-sideslip. Serious degradation of the inlet performance occurred for negative angles-of-attack and angles-of-sideslip greater than 3 degrees. At low subsonic speeds, t...
