This paper presents some experimental results of a bullet impact on composite armor together with numerical modeling approaches. The development of light composite sandwiches for ballistic protection is the target of a project in terms of which the research is being conducted. Traditionally, a vehicle ballistic protection is mainly achieved through metal-based armor which is extremely heavy, hence the increasing popularity of composite sandwiches. Numerical simulations allow for a reduction of the number of experiments needed to obtain appropriate design of ballistic protection, but they require verified modeling approaches and proper material data. Therefore, different modelling approaches for both parts of the composite sandwich have been tested and possibilities to adjust these models to experimental data were investigated.

Abstract The present paper focuses on the numerical modeling approaches adopted in boundary layer ingestion (BLI) studies. Three driving aircraft concepts have been identified, namely propulsive fuselage concept (PFC), rear engines concept (REC), and distributed fans concept (DFC). The affiliation to relevant research projects has been considered. Specifically, European projects DisPURSAL and CENTRELINE, NASA projects STARC-ABL, D8, and N3-X, as well as ONERA projects NOVA and DRAGON have been examined, together with other significant works. The methodologies adopted by the reviewed analyses have been investigated and summarized for each concept, in order to assess the main trends of BLI modeling strategies.
