Hanley Releases Wing-Tail Aerodynamics Calculator

News Hanley Innovations, a small business specializing in aerodynamics and fluid dynamics software development for education and industry, announced today the release of Dr. Hanley’s Aerodynamics: The Wing-Tail Calculator.

The Wing-Tail Calculator was developed using a vortex lattice (vortex rings) CFD method. The program is quite powerful and yet easy-to-use.

Wing-Tail can be used to:

  1. Compute lift-drag coefficients for an isolated wing
  2. Compute lift-drag coefficients for a wing-tail system
  3. Determine neutral points for wing-tail system
  4. Compute trim angle
  5. Compute the aerodynamic coefficients at the trim angle
  6. Simulate ground effect

The Wing-Tail Calculator might also be used to model the lift and vortex drag on a keel-rudder system or perhaps a double sail configuration. In these applications, however, one half of the wing-tail will model the actual device while the other half can model a surface image. (note: no explicit calculations are made in the software for this modification).

Wing-Tail accepts the following inputs for both the wing and tail: span, taper, sweep (forward and back), airfoil (just 4) and angle. The tail can be placed at arbitrary locations along the x-axis. The user must also enter the center of gravity location, profile drag at Cl=0, airplane weight & speed and whether or not to include ground effect in the calculations.

The Wing-Tail Calculation will compute lift, drag and moment coefficients, lift, drag and moment forces, location of the neutral point, mean aerodynamic chords, Cl_alpha, Cm_alpha, lift-drag-ratio and the minimum sink rate.

Wing-Tail can be used as an educational aide for learning about 3-d wings, induced drag, sweep, taper and longitudinal stability. It has 4 different airfoil for experimentation purposes. It is perfect for an introductory aerodynamics course, flight dynamics or aircraft conceptual design.

The introductory price of wing-tail is $29.00. The price at the end of the introductory period will be $45.00. Please purchase the software using the following url: 649332
