Electrothermal de-icing systems are a popular approach to protect unmanned aerial vehicles (UAVs) from the performance degradation caused by in-cloud icing. However, their power and energy requirements must be minimized to make these systems viable for small and medium-sized fixed-wing UAVs. Thermal de-icing systems allow intercycle ice accretions...
In-flight icing on unmanned aerial vehicle (UAV) propellers can lead to severe aerodynamic performance degradation or even complete loss of the UAV. Ice protection systems (IPS) are used to enable the flight of UAVs in icing conditions by protection aerodynamically critical surfaces such as wings and propellers. In this study an electro-thermal ice...
Unmanned aerial vehicles (UAVs), or drones, are increasingly used in diverse commercial and military applications. Ensuring their reliability is crucial to prevent endangering mission targets, people, and infrastructure. All-weather capability is essential for UAVs to operate effectively in various conditions. One major risk is atmospheric icing, w...
div class="section abstract"> Icing is a severe hazard to aircraft and in particular to unmanned aerial vehicles (UAVs). One important activity to understand icing risks is the prediction of ice shapes with simulation tools. Nowadays, several icing computational fluid dynamic (CFD) models exist. Most of these methods have been originally developed...
div class="section abstract"> In-flight icing can result in severe aerodynamic performance penalties for unmanned aerial vehicles. It is therefore important to understand to which extent ice will build up on fixed-wing unmanned aerial vehicles wings and empennages, namely rudder and elevator, and how this ice will impact the aerodynamic performance...
div class="section abstract"> Atmospheric in-flight icing poses a challenge to all aircraft including unmanned aerial vehicles (UAVs). Aircraft should avoid icing conditions unless they have ways of mitigating the negative effects of icing, e.g., if they are equipped with an ice protection system (IPS). When de-icing systems are used, a certain amo...
Ice accretion poses substantial safety hazards for the manned and unmanned aviation industries. Its study is essential for icing events risk assessment and for the development of efficient ice protection systems. The existing ice accretion measurement techniques—casting, molding, and laser-scanning—are time-consuming, sometimes cumbersome to use, a...
View Video Presentation: https://doi.org/10.2514/6.2022-3905.vid Icing encounters can reduce the aerodynamic performance of aircraft significantly. To protect aircraft against the adverse effects of icing, ice protection systems are required. As of today, no mature ice protection systems exist for medium-sized fixed-wing unmanned aerial vehicles (U...
This database gives an overview of the specifications of 93 unmanned aerial vehicles (UAVs). This database can be used to characterize different types of UAVs and their properties. The database contains the following information for each UAV: - Maximum takeoff weight (MTOW) - Payload - Wingspan - Lenght - Cruise speed - Maximum speed - Stall speed...
Atmospheric icing is a key challenge of the operational envelope of unmanned aerial vehicles. Especially medium-sized fixed-wing UAVs suffer from the consequences of ice accretions. Icing wind tunnels are important facilities to do experiments and gain more insight into atmospheric icing. However, the number of suitable icing wind tunnels for UAVs...
