Design of ASLV encompasses aerodynamics, propulsion, structure, stages layout, mass distribution, and trajectory modules connected by multidisciplinary feasible design approach.
The main disciplines taken into account in the platform are related to the launcher's propulsion, structure, aerodynamics, trajectory optimization and costs.
Supersonic flight offered the aeronautical engineer new challenges in propulsion, structures and materials, high-speed aeroelasticity, and transonic, supersonic, and hypersonic aerodynamics.
These communities were strategically aligned with NASA's core competencies in such disciplines as avionics, flight mechanics, life support, propulsion, structures, loads and dynamics, human factors, and guidance, navigation, and control.
The most important selected disciplines to improve the mass and energy characteristics of SLS are propulsion and structure.
First a thorough modelling process which involves the estimation of the aerodynamic and propulsion system structure and parameters is carried out.
Optimal design of an Autonomous Underwater Vehicle (AUV) consists of various subsystems and disciplines such as guidance and control, payload, hydrodynamics, power and propulsion, sizing, structure, trajectory and performance.
Technological issues are also reviewed, focusing on the three major challenge areas associated with these vehicles: aerothermodynamics, propulsion, and structures.
A cooperative program between the National Aeronautics and Space Administration NASAA), the Austrian Space Agency (ASA), Pratt & Whitney, Engineering Evaluation and Design, and Plansee AG was undertaken to determine the feasibility of achieving significant weight reduction of hypersonic propulsion system structures through the utilization of TiAl.
Starting with a list of central issues encountered in combustion, advances are illustrated by examining a selected number of topics of interest to aerospace propulsion: Flame structures and detailed modeling of flames, Turbulent combustion, Cryogenic flames and transcritical combustion, Combustion dynamics, Computational Flame Dynamics.
To deadweight must be added the weight of the ship's structure, propulsion machinery, hull engineering (nonpropulsive machinery), and outfit (fixed items having to do with crew life support).
