Examples of control problems occurring during flight tests of fighter aircraft are well documented. In many cases, the cause of the problem could be characterised as inadequate modelling or other inappropriate treatment of the aeroelastic effects on the vehicle dynamics and/or th
...
Larger power requirements from modern spacecraft precipitate enormous solar arrays to fulfil budgetary needs. Although the solar arrays may have a relatively small influence on the total mass of the spacecraft system, large arrays with long flexible panels do affect the dynamics

UAS will be integrated into the airspace in the near future, but the risk of UAS collision is not well understood which hampers the development of adequate regulations and standards. As risk has two constituents: frequency and consequence, collision risk analysis of UAS operation

Part of the work of AircraftFire, a project investigating the effects of fire and crash on aircraft survivability, is presented. This work compares the effect of changing the material model from metallic to composite on the impact damage and floor acceleration characteristics. Fi

Larger power requirements from modern spacecraft precipitate Brobdingnagian solararrays to fulfil budgetary needs. Although the solar arrays may have a relatively small influence on the total mass of the spacecraft system, large arrays with long flexible panels do affect the dyna

Sensor structural feedback and propellant sloshing have an adverse affect on the stability of conventional launch vehicles. Additionally, vehicle flight loads increase due to structural vibrations. However, in the conceptual design phase of a conventional launch vehicle, it is co
