Task 1: Question No. 1: Area of the aircraft = S = 29 m2 Coefficient of Lift = CL = 0.67 Altitude = A = 29000 ft Velocity = V? = 385 km/hr = 106.94 m/s Lift = L = ? Solution: Density at given altitude ‘A’ = A = 0.4671 kg/m3 (Anderson Introduction 763) Lift on an airfoil is given as L = (?…

Introduction

2: Coefficient of Drag = CD = 0.054 Area = S = 15 m2 Thrust = T= 1500 N Density= A = 0.5 kg/m3 For a steady and level flight, drag force is equal to the thrust produced by engines, D = T = 1500 N D = (? A V?2) S CD = (? (0.5) (V?2)) (15) (0.054) = 1500 => V? = 86.06 m/s = 8.6 E +1 m/s Question No. 3: Question No. 4: The sketches shown below illustrate the trend of variation in CL, CD, and L/D ratios with increasing angle of attack. Question No. 5: Critical Mach number corresponds to that value of Mach number for free stream flow for which a localized mach number of ‘1’ is obtained at any point around the airfoil. When this condition arises, a shock wave is created at the point where the flow reaches the sonic speed. As the speed increases, regions of very low pressure are created. This causes the flow to separate from the airfoil thereby substantially increasing the drag forces on it. The figure illustrates this phenomenon. Some of the important design features incorporated in the aircrafts in order to contain the effects of this situation are using thin airfoil and / or super critical airfoil (Anderson Introduction 763). Making an airfoil thinner increases the value of Critical Mach Number and hence the airplane can fly at very high speeds without a significant increase in drag forces on it. ...

In this case, to solve the alcohol abuse problem, one has to consider marginal benefits and marginal costs derived from consuming an extra unit of alcohol and since excessive drinking has more costs than benefits, one would refrain from alcohol. The opportunity cost foregone by choosing to abuse alcohol is too high compared to satisfaction derived; money spent on alcohol can do many other things…

In this paper, the control surfaces are shown in a typical aircraft along with their uses. Motion about the longitudinal axis is produced through ailerons. Ailerons are installed in both the wings. To tilt an aircraft in one direction, one of the hinged ailerons moves up while the other moves down. A significant drag acts on the flat ailerons that produce a moment around the longitudinal and…

Discussion The first principle discusses the competitive financial environment. This principle outlines four factors that affect the business environment. These are: the principle of self-interest behaviour, the principle of two-sided transactions, the signalling principle and the behavioural principle (Emery, Finnerty and Stowe, 2007). The principle of self-interest means that the company will…

It can be explained as, if one of the asset in the portfolio is giving negative return, then it would not have a significant impact on the overall return of the portfolio because the other assets might be performing well and thus making up for the asset which is not performing well. Diversification helps an investor to have consistent return on its portfolio over a period of time. An investor who…
