Airplane design

Formulate conceptual design of aeronautical or aerospace products or systems to meet customer requirements or conform to environmental regulations. ... Plan or coordinate activities concerned with investigating and resolving customers' reports of technical problems with aircraft or aerospace vehicles.

Flight dynamics I - Airplane performance

Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space.[1] It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.For a fixed-wing aircraft, its changing orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing("alpha") and the angle of attack of the vertical tail, known as the sideslip angle("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, ie the centre of gravity moves sideways.[2] These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft.Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earth's or any other atmosphere).

Flight dynamics II - Airplane stability ..

Here we will limit ourselves to the inherent stability of the aircraft. Hence the aircraft is said to be stable if it returns back to its original equilibrium state after a small perturbing displacement, without the pilot intervening. Thus, the aircraft's response arises purely from the inherent design.

Introduction to Turbulent Flows and thei..

In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes ..... A similar effect is created by the introduction of a stream of higher velocity ... This ability to predict the onset of turbulent flow is an important design tool for ..... There is considerable evidence that turbulent flows deviate from this
