dc.description.abstract | Crashworthiness model for Korean Utility Helicopter was built by employing KRASH, a kinetic analysis program, and the characteristics and performance of crashworthiness were assessed by the analysis. As a result of the analysis considering crashworthiness impact velocity of military standard, the vertical impact velocity became 0 after 0.124 second and the predicted values for the maximum acceleration of the engine and power transmission gear were 33G and 27G respectively. Cabin space height before and after the crash were 1.59 m and 1.40 m respectively; it led to 12% reduction in survival space but managed to fulfill the engineering requirement of "below 15%." The predicted maximum displacement of crew and passenger seats were 126 mm and 188 mm respectively, fulfilling each of the acceptable standard. In addition, according to the results evaluated by Eiband Curve, passenger acceleration level was found out to be insufficient to cause a severe damage to passengers. | - |
