N2 - Drag modelling forms an important part of a simulator flight model. A method of formulating and implementing a landing gear drag model has been developed. A theoretical estimate of the drag of landing gear of an aircraft in the class of the Airbus A320 and Boeing 737-800 has been determined using textbook procedures presented by Raymer (2006) and Torenbeek (1982). The results were successfully coded into the flight modelling software, JSBSim, using XML (Extensible Mark Up Language). For testing and validation, FlightGear, a simulation software package, was used to observe the response from the JSBSim landing gear drag model. The output of the JSBSim gear drag model showed a good correlation with the theory of gear drag dynamics. The theoretical method used to describe the landing gear drag, demonstrated that the landing gear drag coefficient reduces as the lift coefficient increases; this observation was supported by available data from a flight test for the B747-100.
