UAV Aerodynamics Conceptual Analysis

MultiSurface Aerodynamics is an aerodynamics conceptual & preliminary design and analysis software for unmanned aerial vehicles (UAV) wings and control surfaces. Improved designs start with efficient airfoils and wings optimized for low drag, high endurance and low visibility.

Although UAV conceptual aerodynamics analysis is for the most part similar to that of manned aircraft, some designs requirements are unique for high altitude, long-endurance vehicles or HALE UAVs (Global Hawk, for example) or small reconnaissance vehicles (Dragon Eye, for example). MultiSurface Aerodynamics has built-in capabilities and features that makes it an ideal aerodynamics analysis & design tool for conventional or unconventional unmanned aerial vehicles:

Benefits of MultiSurface Aerodynamics
Start designing immediately. Enter new concepts into you PC and get immediate feedback on the feasibility of the design.
No advance knowledge of aerodynamics or mathematics needed for conceptual or preliminary analysis.
Accurate results. You can reduce time in wind tunnel and flight test.
Familiar Windows user interface. MultiSurface Aerodynamics is an easy-to-use software package.

Typical UAV Problems Solved by MultiSurface Aerodynamics
Short endurance due to poor airfoil & wing design.
Poor flying qualities due to stability issues. This problems renders the aircraft flyable by just a few skilled pilots.
Fast landings that damage equipment & cause loss of valuable data.
Long takeoff distance that compromise operations.
Large aerodynamic surfaces that increase weight, reduce structural integrity and restrict the portability of the aircraft.

MultiSurface Aerodynamics Features
Airfoil analysis of moderate (~100 K) to high Reynolds number flows. See here for example ...
Airfoil analysis to predict transition and flow separation. Design cleaner wings that increase endurance.
Isolated wing analysis (for high and low aspect ratio wings). Optimize wing size and with respect to load capacity and drag reduction.
Wing and tailplane analysis. Reduce trim drag and increase aircraft endurance & range.
Canard, wing and tailplane analysis. Improve the takeoff, landing and stability of the aircraft.
Analysis of wings with varying degree of sweep
Analysis of joined wings or multiple wing planforms. Optimize lifting surface size  and configuration to reduce weight while improving endurance & range. See here for example ...
Analysis of oblique wings
Analysis of nonplanar lifting systems such as winglets and multiple dihedral planforms. Reduce wing size with winglets and other devices.
