The design and mission requirements of aero vehicles, which vary on a day-to-day basis, have become major study concerns in the burgeoning aviation sector. In addition to the design and mission criteria that must be met in an aero vehicle design, the designers' primary goals are to construct original, …

BACKGROUND: Efficient communication between (helicopter) emergency medical services ((H)EMS) and healthcare professionals in the emergency department (ED) is essential to facilitate appropriate team mobilization and preparation for critically ill patients. A correct estimated time of arrival (ETA) is …

The potential benefits of using redundant controls on a compound helicopter for manoeuvre load alleviation whilst optimizing handling qualities are investigated. The research is focused on forward flight lateral (roll) manoeuvres and hub loads. The main control effectors of interest are the ailerons …

Rotor morphing has been investigated in the past for improvement of rotor performance, either for reduction of rotor power demand or for vibratory load alleviation. The present study investigates the application of camber morphing for improvement of rotor performance in hover and vertical flight conditions, …

The author discusses how helicopters may fly autonomously using fuzzy logic, without crashing too often. He reviewes the added value of sensor fusion in military observation systems. Sensor fusion is motivated by the expected qualitative and quantitative improvement of observations and thus of situation …

In Engelstalige literatuur wordt er wel over ‘helicopter parents’ gesproken. Helikopterouders zijn ouders die voortdurend ‘boven de hoofden van hun kinderen hangen’, constant toezicht houden op elk aspect van hun leven.  In: Nieuwsbrief Nederlandse Dalton Vereniging, november 2018

For the simulation of a flexible helicopter rotor system the Euler equations for a rotating and translating beam structure are derived using the Finite Element technique. Using the displacements and velocities of a beam element which has an airfoil shaped cross section the aerodynamic forces and moments …

Pain is one of the main complaints of trauma patients in (pre-hospital) emergency medicine. Significant deficiencies in pain management in emergency medicine have been identified. No evidence-based protocols or guidelines have been developed so far, addressing effectiveness and safety issues, taking …

Collaboration in organizations is not a new phenomenon indeed. Processes in organizations have always required collaboration and co-ordination between people, activities and departments. The last few years, however, there has also been increased co-operation between organizations, the so-called inter-organizational …
