• The pyrometer fitted for the temperature measurement of exhaust gas of the rocket, was constructed, and the exhaust temperature of the JP4-nitric acid rocket having 100 kg. of thrust, was observed. From the obtained exhaust temperature, it has been ascertained that the expansion of the gas through the present nozzle proceeds with chemical equilibria neither shifting nor frozen, and that relaxation occurs. From the approximate analysis of chemically relaxed flow, the relaxational process is assumed to occur at －(<I>dt</I>⁄<I>dT</I>)=3∼8×10<SUP>－8</SUP> sec./deg., <I>T</I>\fallingdotseq2600°K and <I>T</I>\fallingdotseq10 atm.
