I am designing an obscuration device for development bird strike testing of machined frames within the NLG bay of an aircraft. The device is to encompass the volume of the actual NLG. Are there any approximate equations that can be used to determine the impact stress on the steel dummy component. Currently the only information I have is supposedly only accurate for heavy object at low speed, the scenario under test is light object (<2kg) at high impact speed (130m/s).
Any help would be much appreciated.
