Optimal Aftertreatment Pre-Heat Strategy for Minimum Tailpipe NO x Around Green Zones

Green zones are challenging problems for the thermal management systems of hybrid vehicles. This is because within the green zone the engine is turned off, and the only way to keep the aftertreatment system warm is lost. This means that there is a risk of leaving the green zone with a cold and ineffective aftertreatment system, resulting in high...

Tactile cueing effects on performance in simulated aerial combat with high acceleration

Introduction: Recent evidence indicates that vibrotactile displays can potentially reduce the risk of sensory and cognitive overload. Before these displays can be introduced in super agile aircraft, it must be ascertained that vibratory stimuli can be sensed and interpreted by pilots subjected to high G loads. Methods: Each of 9 pilots...

Vibrotactile and visual threat cueing with high g threat intercept in dynamic flight simulation

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...
