APPLICATION OF HEAT STRESS TO ROCKET COWLS OF NONMETALS Russian patent published in 2014 - IPC G01M9/04 G01N25/72 

Abstract RU 2517790 C1

FIELD: aircraft engineering.

SUBSTANCE: proposed method comprises heating of cowl outer surface by electric current fed through heater equidistant from said surface. Said heater is composed by current conducting thin-wall shell varying in height and staying in contact with heat-isolated limiter also equidistant from cowl outer surface. Besides, it comprises temperature measurement. Said by current conducting thin-wall shell is arranged with clearance with respect to cowl outer surface for pressurised inert gas to be forced thereto. Said heat-isolated limiter is made of porous material.

EFFECT: expanded temperature range of heat field reproduction on cowl outer surface at surface tryout of the design.
