| 摘 要： | 1引言超燃冲压发动机能高速飞行且能利用空气中的氧气作氧化剂,增加了有效载荷,因而备受重视,但它需要在较高的飞行马赫数下才能工作,因此受到较大的限制。由于双模态超燃冲压发动机可以将工作飞行马赫数下限降低至Ma=3,发动机在飞行马赫数Ma=3~6时以亚燃冲压模态工作,在马赫数

| Abstract: | To study the variable geometry effects on the dual mode scramjet operation,the mode translation with different ER(equivalence ratio) and the influence on the ignition ability and combustion efficiency of variable geometry dual mode scramjet were investigated by experimental method.The results revealed that the variable geometry can improve the ignition ability,flame holding ability and combustion efficiency and make the mode translation procedure quickly.However,it can also influence the ignition and flame holding process. |

| Keywords: | Supersonic combustion ramjet engine Mode translation~+ Variable geometry~+ Ignition Combustion performance |
