Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] Such as Figure 1-6 As shown, the radial intake distortion suppression grid of the ramjet is installed in the internal flow channel of the ramjet, and the conventional ramjet is composed of a diffuser 1, a combustion chamber 2 and an exhaust nozzle 3, wherein the inlet cross section of the combustion chamber 2 is round. The ramjet radial intake distortion suppression grille 4 is installed at the entrance of the combustion chamber 2 .
[0034] The radial intake distortion suppression grid of the ramjet is provided with a first distortion suppression grid piece 5 and a second distortion suppression grid piece 6, and the first distortion suppression grid piece 5 and the second distortion suppression grid piece 6 share Shafts are stacked together, the first distortion suppression grid sheet 5 is composed of a flexible spiral sheet around the central drum...
