Aerodynamic characteristics of an aircraft – level flight and turn

TS-11 Iskra. Based on them, the stall speed, as well as the minimum and maximum level flight speeds in various configurations, were determined. A performance diagram for the aircraft in a turn and a flight capability diagram for the aircraft were developed.1. INTRODUCTION
Criteria are used to define the features and functions of an aircraft. One of them is performance, which consists of measurable parameters characterizing the movement of an aircraft in space.
For an aircraft to move in space, specific forces are necessary, the value of which results from the design capabilities of a given aircraft (thrust of the propulsion system, type of fuselage, position and shape of the airfoils, wing area, type of empennage, etc.). Knowledge of the aforementioned parameters allows for the estimation of the flight capabilities of a given aircraft.
