Abstract: This paper presents an accuracy analysis for a new ballistic limit equation (BLE) developed by our group for Whipple shield. The results are compared with those based on the newest Christiansen BLE developed by NASA’s Johnson Space Center. It is shown that the accuracy of our new BLE reaches 78% in predicting a large number of domestic and foreign HVI tests, while with the NASA’s BLE the accuracy reaches only 72%. Especially for more than 200 domestic tests, the accuracies are 78% and 61%, respectively. Therefore, our new BLE enjoys high accuracy and universal applicability for domestic and foreign materials, and can meet the requirements in engineering applications. Our new BLE effectively improves the accuracy and overcomes the compatibility problem of the NASA’s BLE, and can provide a technical support for engineers in designing shields and conducting risk assessment for China’s future space stations.
