Development of Modern Transport Aircraft Introduction This document is presented to compare the two commercially successful and super-efficient airplanes‚ the Boeing 707-320B and Boeing 787-9. This document will identify the key innovations in airframe and propulsion technology‚ and also further discuss on why the basic design and appearance of aircraft remain unchanged over 50years.

BREAK EVEN ANALYSIS Introduction Break-even analysis is a technique widely used by production management and management accountants. It is based on categorising production costs between those which are "variable" (costs that change when the production output changes) and those that are "fixed" (costs not directly related to the volume of production). Total variable and fixed costs are compared with sales revenue in order to determine the level of sales volume‚ sales value or production at which

most extreme load which is closest to critical pressures for distortion‚ as shown in figure (3.4). Hence using this loading‚ the aircraft will be in the safe region from distortion during a flight.

CHAPTER 1: INTRODUCTION 1.0 Introduction Corrosion is the gradual destruction of material‚ usually metals‚ by chemical reaction with its environment. The destruction or degradation implies deterioration of physical properties of the material. This can be a weakening of the material due to a loss of cross-sectional area‚ it can be the shattering of a metal due to hydrogen embrittlement‚ or it can be the cracking of a polymer due to sunlight exposure. So as long the metal is not be stored properly

the first powered airplane 20 feet above a wind-swept beach in North Carolina. The flight lasted 12 seconds and covered 120 feet. This event would change modern transportation forever. The 1903 Wright Flyer made four flights at Kitty Hawk‚ North Carolina‚ on December 17‚ 1903‚ the best covering 852 feet in 59 seconds. It was the first heavier-than-air‚ powered aircraft to make a sustained‚ controlled flight with a pilot aboard. The Wrights used their proven canard biplane configuration‚ which was

Executive Summary Goodrich Company was suspected of publishing falsified qualification report of its new-designed aircraft brake for the A7D. Kermit Vandiveer‚ a data analyst and technical writer in Goodrich‚ was ordered by the executives to issue a false qualification report. Initially‚ Vandiveer refused and got support from his supervisor. However‚ under the pressure he had to offered artificial graphic presentation in the report. After the failing flight test‚ Vandiveer disclosed the misconduct

TECHNICAL PAPER (FINAL): - EXTERIOR AIRCRAFT LIGHTING SYSTEMS Exterior Aircraft Lighting Systems Author: Peter Mann Abstract There are many forms of lighting on an aircraft and each has its own purpose. Aircraft lighting can be split into two distinct categories: exterior and interior. This technical paper will look at exterior aircraft lighting systems. It will examine the purposes of these exterior lighting systems‚ their implications on the aircraft as a system of systems‚ and the

Transportation of Cargo on Passenger Aircraft Embry Riddle Aeronautical University Abstract This paper provides information into the lack of aviation security with regard to cargo transported on passenger aircraft. Passengers and their luggage traveling on aircraft are subject to screening‚ security searches and body scanning prior to boarding. However‚ the cargo loaded may not have been inspected‚ allowing for potential security vulnerabilities to be exploited. Currently international flights

occur due to many factors. An aviation accident is the worst nightmare of every pilot or passenger that has ever ridden in an aircraft. Although air travel is one of the safest forms of transportation‚ accidents do happen with dramatic and terrifying results. The causes of these aviation accidents vary greatly depending on specific circumstances and problems that may develop during the flight process. Weather is one of the factors that can influence an aircraft accident in a number of ways. There
