“…The physics-based sizing models are generated using M4 Structures Studio. M4 Structures Studio has been used to build structural weight prediction models for a variety of UAM configurations [73][74][75] and has been validated against a variety of historical aircraft weight data. M4 Structures Studio is a parameterized structural modeling tool that creates structural sizing finite element models for NASTRAN.…”

“…Aluminium matrix composites (AMCs) reinforced by SiC particles have tremendous applications in aerospace [1][2][3], electric vehicles [3][4][5][6] and urban air mobility [7] due to the excellent mechanical and thermal properties of SiC. Generally, the final performance of the AMCs depends on the volume fraction, size and dispersion of reinforcements.…”

In the present study, the composite sheets were produced by powder rolling the ball-milled Al/ SiC mixture. The effect of milling speed (350-550 rev min -1 ) and milling duration (8 and 12 h) on the Al particle morphology and subsequent mechanical properties were examined for composites with different volume fractions of SiC. From the microstructural investigation, SiC particles are evenly distributed and well dispersed in the Al matrix; those are prepared under higher milling speed (550 rev min -1 ) and higher milling time (12 h). Furthermore, the flattened-shaped particle morphology was obtained under lower milling conditions, whereas the reduced-granule shape was obtained under higher milling conditions (550 rev min -1 , 12 h). Consequently, the Al/SiC composite sheets made from a granule-shaped Al/SiC mixture show higher density, microhardness, and tensile strength due to significant consolidation and SiC uniformity. In addition, the tensile strength of 430.26 MPa has been achieved for the Al/2vol.-%SiC sheet compared to pure Al (393.49 MPa) under similar processing conditions.

NASA is conducting investigations in Advanced Air Mobility (AAM) aircraft and operations. AAM missions are characterised by ranges below 300 nm, including rural and urban operations, passenger carrying as well as cargo delivery. Urban Air Mobility (UAM) is a subset of AAM and is the segment that is projected to have the most economic benefit and be the most difficult to develop. The NASA Revolutionary Vertical Lift Technology project is developing UAM VTOL aircraft designs that can be used to focus and guide research activities in support of aircraft development for emerging aviation markets. These NASA concept vehicles encompass relevant UAM features and technologies, including propulsion architectures, highly efficient yet quiet rotors, and aircraft aerodynamic performance and interactions. The configurations adopted are generic, intentionally different in appearance and design detail from prominent industry arrangements. Already these UAM concept aircraft have been used in numerous engineering investigations, including work on meeting safety requirements, achieving good handling qualities, and reducing noise below helicopter certification levels. Focusing on the concept vehicles, observations are made regarding the engineering of Advanced Air Mobility aircraft.
