Based on numerical investigation

the characteristics and design method of ramjet engine combustor with inclined multihole heat shield was researched.First

the temperature distribution of ramjet engine combustor with no-hole heat shield was calculated

and then

according to the temperature distribution

the array of inclined holes in the heat shield (plan A) was designed

after that

the temperature distribution of inclined multihole heat shield was calculated.Using similar methods after two more distribution improvements (plan B and plan C)

the non-uniform distributed solutions of inclined multihole which met the demand for the cooling was obtained.The results show that using the design approach in cooling flow reduced from 17.45% of plan A to 14.99 % of the plan C

the lowest cooling efficiency of inclined multihole heat shield improves from 70% of plan A to 85% of plan C.
