Overview
AID is an academic tool intended to assist in developing an intuitive understanding of
aircraft stability and control. By interfacing user-friendly aircraft modeling with rapid
aerodynamic analysis, this program visually depicts how various design parameters
affect the way an airplane flies.
Numerous geometric and aerodynamic parameters (i.e., planform shape, airfoil type,
general configuration) must be tuned throughout the preliminary design phase, and
knowing how these values influence a plane’s stability is critical in making educated
decisions to meet design goals. This program helps provide the user with this
understanding, while also greatly reducing the time spent on trade studies between
different wing/tail placements, planform shapes, and several other design
considerations.
From the moment the program is first opened, several calculations have already been
performed estimating the lift, drag, and moment of each planform and body, as well as
many of the stability derivatives characterizing the aircrafts flight. In addition to these
built-in, linearized stability approximations that are constantly being updated, the
program interfaces with the following software for more advanced analysis:
USAF Digital DATCOM
Tornado Vortex Lattice Method
AVL (Athena Vortex Lattice Method)
Note: While the majority of the inputs and outputs for these programs are written/read in automatically, the user is still
encouraged to glance through the input/output files for errors by selecting Settings > Inputs/Outputs.
This program also gains added functionality from the following open source software:
DATCOM Plot Interpolation Functions – Prof. Glen Greiner and Lenny
Gartenberg (Embry-Riddle Aeronautical University, Daytona Beach, FL)
AVL Input/Output Functions – Joseph Moster (Mathworks File Exchange)
Datcomimport – MathWorks Aerospace Toolbox – loads DATCOM for006.dat
NACA456 – Ralph Carmichael (PDAS) – NACA 6-series airfoil ordinates
