Validation method for numerical simulations of large objects using the T-matrix for a collection of scatterers

Abstract: This paper presents a validation method for large-scale electromagnetic scattering simulation problems, especially such performed using the Finite-Difference Time-Domain (FDTD) method. Large computational volumes imply that the results suffer from numerical dispersion. In order to validate the simulation results for large geometries a T-matrix solution for a collection of spheres can be used. In this paper the solution has been restriced to two spheres separated along the z-axis. Monostatic and bistatic scattering results using FDTD and the T-matrix method are compared. It is concluded that the grid resolution in FDTD must be adjusted in order to maintain the accuracy if the size of the computational volume increases substantially.

Device at a launcher at an air vehicle

Abstract: A device at a launcher at an air vehicle for detachably carrying and guiding a missile or the like is shown. The launcher comprises means for detachably carrying the missile and means for guiding the missile in the longitudinal direction of the launcher. The latter comprises a first profile element secured in the launcher and a second profile element secured in the missile, which profile elements are arranged to interact in order to admit a free mutual movement in the longitudinal direction of the launcher, while movement in lateral directions is limited. The device according to the invention is characterized particularly in that it comprises a profile plate and a number of rela-tively thin shims , the profile plate and shims being arranged securable in the first profile element to so limit by means of an appropriate number of shims the mutual move-ment of the first and the second profile element in the load carrying direction across the longitudinal direction of the launcher that the required allowance between the profile ele-ments for mutual movability or the profile elements in the longitudinal direction of the launcher is maintained.

ACE: advanced cockpit technologies evaluation

Abstract: The development of data generating sensors and computers in a modern fixed wing aircraft is not met by an increase in sensorial performance by the operator to assimilate this data. No new sensor has been developed nor has any drastic increase in data perception been implemented in the human operator since the first manned flight by the Wright brothers. Consequently we have to refine the media and the way in which we present data to the pilot. This document describes a platform for test and evaluation of head mounted technology and some new technologies that can be used for decreasing the pilot's workload. Furthermore, the document describes initial tests done on image quality and design of reflective coatings on visors.
