OCALA, Florida, July 29, 2002 - 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 AeroTrajectory, a user-friendly software package for computing the trajectory of objects subjected to aerodynamics forces during flight. AeroTrajectory runs on a PC under Windows 95/98/NT/2000/XP.

AeroTrajectory is intended for use in classroom as a virtual lab tool at the K-12 and undergraduate levels. It is an indispensable reference tool for engineers, scientists, designers and other physics enthusiasts.

The user can enter a lift and drag coefficient along with a reference area to simulate the aerodynamic forces. Also required is the medium density, wind speed and direction, the object’s mass and the acceleration due to gravity (i.e. simulations can be done on Mars or other planets). The user can set initial conditions on the object Velocity, Height, Range and Simulation Start Time. Furthermore, the user can set a Net Thrust and Normal Force at (y=0). The Normal Force condition sets an optional boundary condition along the x-axis where the object’s weight can be supported. This was done to simulate the Take Off of an airplane.

AeroTrajectory has a dialog box that allows the user to select the stop conditions of the simulation. For example, the user can stop the simulation at a specific time, height (descending or ascending) or range. The user can also start the simulations again by clicking a button in the Input dialog box to automatically capture the end conditions of the last simulation and set them as the new initial conditions.

The retail price of AeroTrajectory is $45.00. The software can be purchased online and obtained electronically from: http://secure.emetrix.com/order/product.asp?PID=7861423
