The purpose of the paper is to present some approximate criteria for assessment of a light tail-aft aircraft configuration from the point of view of its properties in stall and spin. In some cases, compilation and/or modification of methods presented in literature is proposed.
The paper is divided into two parts:
– Stall characteristics. This part is focused on determination the spanwise distribution of a lift coefficient over a wing and setting some additional criteria. Fulfillment of these criteria determines the aircraft performance in stall and pro-spin conditions.
– Spin characteristics. Some rough criteria for evaluation of an aircraft arrangement accounting its spin characteristics are given. A simplified mathematical model of motion in spin with approximate methods for determination of necessary aerodynamic coefficients is presented.
