Independent Verification and Validation of Software for Weapon Management System of a High Performance Aircraft

The failure of safety critical embedded software is unacceptable be it for safety, security or economic reasons. The risk of software failure in complex embedded systems is overcome by using the Independent Verification and Validation (IV&V) technique. The process of IV&V and its planning needs to be initiated early in the development life cycle of the weapon management system for a high perfor...

High-Order Discontinuous Galerkin Methods for Turbulent High-lift Flows

In this work a robust discontinuous Galerkin (DG) solver for turbulent high-lift aerodynamic flows using the turbulence model of Spalart and Allmaras (SA) is developed. The application of DG discretizations to turbulent RANS flows is one of the most pressing issues facing high-order methods on unstructured grids. The issue is the result of non-smooth behavior of the turbulence model equation, w...

Approach Considerations in Aircraft with High-Lift Propeller Systems

NASA’s research into distributed electric propulsion (DEP) includes the design and development of the X-57 Maxwell aircraft. This aircraft has two distinct types of DEP: wingtip propellers and high-lift propellers. This paper focuses on the unique opportunities and challenges that the high-lift propellers—i.e., the small diameter propellers distributed upstream of the wing leading edge to augme...
