Abstract Blended-Wing-Body (BWB) represents a promising direction for future civil aircraft design due to its high aerodynamic efficiency. This study examines Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS)-based BWB civil aircraft's crashworthiness. Major components, including engines, landing gears, and cabin interiors, are modeled as mass points and rigidly connected. Simulations were conducted to understand the aircraft's dynamic response under various crash scenarios, evaluating survivability, passenger acceleration response, and emergency evacuation feasibility. Results indicate that under specified crash conditions (vertical speed of 6–10 m/s, roll angle of 0°-15° and pitch angle of ±10°), significant deformation occurs in the cabin's lower part and the central body's side structures, potentially impeding emergency evacuations. These insights are crucial for enhancing BWB civil aircraft's crashworthiness and offer vital data for future structural designs.
