The methodology uses empirical relationships for flap lift effectiveness, chord extension, drag-coefficient increment and maximum lift coefficient of various types of flap systems as a function of flap deflection, and combines.

To study the effects of ice accretion on the longitudinal aerodynamic characteristics of an aircraft, a two-part method for predicting longitudinal aerodynamic derivatives of iced aircraft is proposed. For the aircraft with a flight test, a parameter identification system based on maximum likelihood criterion and a longitudinal nonlinear flight dynamics model is established.

where λ – the effective wing aspect ratio, C f – skin friction coefficient, \({\overline{S}}_{wetted} \) – the wetted surface area of aircraft divided by wing area. Thus, there are another three directions of flying vehicle economical characteristics improvement, related to aerodynamics: aspect ratio increase, friction drag reduction and aircraft relative wetted area decrease.

Aerodynamics, from Greek ἀήρ aero (air) + δυναμική (dynamics), is the study of motion of air, particularly when affected by a solid object, such as an airplane wing. It is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these term aerodynamics is often used synonymously with gas dynamics, the difference being that.

Traditionally, the methods used to make these calculations are generally known as panel methods and vortex lattice methods.

The theory is described in the notes for Applied Computational Aerodynamics, Chapters 4 and 6. Although we are addressing the aerodynamic features, we will provide brief overviews of the methods used to compute the results. Aeroelasticity involves not just the external aerodynamic loads and the way they change but also the structural, damping and mass characteristics of the aircraft.

Prediction involves making a mathematical model of the aircraft as a series of masses connected by springs and dampers which are tuned to represent the dynamic characteristics of the. Semiempirical method for prediction of aerodynamic forces and moments on a steadily spinning light airplane A semi-empirical method is presented for the estimation of aerodynamic forces and moments acting on a steadily spinning (rotating) light airplane.
