Abstract :
Performance estimation of an aircraft is required to make sure of the ability of the aircraft to perform conventional and mission specific maneuvers. An aircraft`s maneuverability is defined by its capability to alter attitude and speed along its three axes: longitudinal, lateral, and vertical. To acquire the performance of the aircraft for the establishing the operational envelope, initial operation certification and gradual expansion of the flight envelope, an aircraft system is studied directly by conducting some experiments with it or by using its mathematical model. Nowadays, mathematical modelling is more preferred over real flight testing as rehearsal of several situations cannot be practiced in real life. Further, drastically reduced training costs and increased efficiency of the required results. The conceptual model of the specific static maneuvers of the aircrafts can be converted to computer model via programming in a flight simulator such as Matlab, which then simulates the reality. The maneuvering capabilities of an aircraft are decided according to the mission to be performed. Therefore, the commercial passenger aircrafts are more stable and less maneuverable compared to the commercial transport and the military aircrafts, designed so keeping in mind the passenger safety and security as the foremost aim. Hence, it becomes very important to estimate the responses of a commercial aircraft for the maneuvers it performs under its operational flight envelope. Such estimation firstly requires a study of these maneuvers. Secondly, converting them into a matrix model and then simulating them in the Matrix Laboratory to obtain the required results for further analysis to arrive at conclusions. The conclusions required from the flight simulator are the coefficient of lift, drag; load factor, velocity and time estimation for a particular maneuver that an aircraft is capable to perform.
