“…In recent years, the Computational Fluid Dynamics (CFD) technology has been successfully applied to numerically simulate the complicated flow for the propeller-driven aircraft or the rotorcraft. There are mainly three kinds of methods that have been developed, including the actuator disc method (2)(3)(4) , the Multiple Reference Frame method (5) and the unsteady sliding mesh method (6,7) . Although the CFD method has a high fidelity in predicting the propellerwing interference behaviour, its computational cost limits its own applications at conceptual and preliminary design stages of an aircraft.…”

For aircraft that employ distributed propeller propulsion systems, the distributed propeller slipstream increases the analysis complexity. The objective of this paper is to rapidly analyse the influence of propeller slipstream on a wing using a fast prediction approach to perform conceptual design studies. This fast approach is implemented through a panel/viscous vortex particle hybrid method taking into account the air viscosity effect. The parametric studies of propeller streamwise, spanwise, vertical installed position, propeller number and rotational direction are conducted for a rectangular wing platform in two different propeller-wing configurations. The results indicate that the propeller slipstream causes both the augmentations of the wing lift and drag in a traditional tractor propeller layout. For an over-the-wing propeller configuration, however, the obvious lift increase and drag decrease can be obtained. A rear propeller position relative to the wing chord leads to a beneficial increase in lift while a fore propeller location is able to decrease the wing drag. The maximum increment of the lift-to-drag ratio can be achieved by 17.6% when the propeller is located at 30% of the wing chord, which shows a considerable advantage in improving the wing aerodynamic efficiency.

In this paper, we report our progress on integrating a model‐based system engineering methodology with a system architectural trade study applied to flight control systems of a locally owned and operated, cost effective Unmanned Aerial Vehicles (UAV) design utilizing the concepts of Model‐Based Systems Architecture Processes (MBSAP). The primary objective of the UAV is to monitor wildfires and to gather information and to provide surveillance data for predicting and preventing wildfires [1]. We describe our experience with a holistic approach to architect flight controls (the System‐of‐Interest), in a way that is tightly coupled with high‐level stakeholder needs and concerns, operational scenarios, (normal, inadvertent, and mis‐) use cases, Context System, and Enabling Systems.Several architectural variants of the Surface‐less Flight Controls (SFC) were traded. Our systemic approach showed that classical flight controls are feasible for the baseline UAV. It also helped us identify a novel architecture with a potential to drastically improve UAV performance (range, survey time), UAV weight, and specific cost. Our approach has resulted in an architecture that has the potential to significantly reduce the costs of manufacturing as well as operating UAVs, at the same time it drastically improves their performance. This development could mean widely increased availability and improved effectiveness of UAVs in fire detection and prevention.
