BEM (Bladed Element Momentum) models have shown to be inaccurate in predicting loads in the case of yawed flow [1-3]. Actuator disk momentum theory is the basis for BEM codes, following Glauert's auto-gyro theory [4]. Therefore, a first step to improve BEM in yawed flow is to assess momentum models for the actuator disk in yaw and investigate...

Data show that spatial orientation in microgravity differs from that on Earth possibly facilitating space motion sickness and degrading performance. As a technology demonstration, we developed a Tactile Orientation Awareness Support Tool (TOAST) consisting of a vest with 56 vibrators. TOAST presents an artificial gravity vector by a localised...

In a TNO and FOI joint study, nine fighter pilots participated in a threat detection and intercept experiment in the Swedish Dynamic Flight Simulator. Visual threat cueing with a simulated Gripen aircraft head-up display (HUD) symbology was compared with combined visual and vibrotactile threat cueing by means of the HUD symbology and a TNO...

The three Dutch research institutes NLR, TNO and TU Delft are collaborating to perform a multi-simulator follow-up study aimed at investigating the influence of yaw and translational motion cues in helicopter- and general flight-simulation. In this study, new experimental results will be combined with pilot modeling. Two experiments will be...

Many countries are developing technologies for future hypersonic air breathing cruise missiles. These missiles are foreseen to be employed against, amongst others, deeply buried targets. The main technological challenges are related to severe aerodynamic heating and complex physical processes of aerodynamics and combustion at hypersonic flight...

In this paper, the authors propose to introduce and describe a newly developed precise tightly-coupled integrated navigation system. The performed experiments with the purpose of evaluating the system performance are shown. A complete description of the integrated navigation system hardware, including calibration details, and software, with...

The ducted rocket is a supersonic flight propulsion system that takes the exhaust from a solid fuel gas generator, mixes it with air, and burns it to produce thrust. To develop such systems, the use of numerical models based on computational fluid dynamics (CFD) has been increasing, but to date only simplified treatments of the combustion within...
