Abstract The crash-worthiness design of civil transport aircraft fuel systems is significance to improve the safety in case a crash. CCAR25.993 (f) requires that “fuel feed line fuselage shall be assembled allow reasonable deformation and tension without leakage”. Fuel system supply with appropriate hose configuration can take advantage ductility material, guillotine test accepted by worldwide ...

Most current insect research techniques are ground-based and provide scarce information about flying insects in the planetary boundary layer (PBL), which remains a poorly studied ecological niche. To address this gap, we developed new insect-sampling method consisting of fixed-wing drone platform with net traps attached to fuselage, mobile design that has optimal aerodynamic characteristics for...

The inflow distortion to the fan introduced by ingestion of fuselage boundary layer is most critical challenge in realizing benefits later ingesting (BLI) concepts. Minimizing level while maintaining desired amount ingested and free stream flow crucial minimizing penalties efficiency noise emissions. In this paper, a parametric sensitivity study performed examine integration two semi-buried BLI...
