This project is intended to give the student an improved understanding of aircraft dynamic behavior thought the use of a SIMULINK flight simulation. The student is to use knowledge of flying and handling qualities to appropriately grade a certain maneuver, of a certain aircraft, under a certain condition. The student is to modify the performance of an aircraft through the implementation of a control law.
For the purposed of this project, the aircraft in question will be a Convair 880 at an altitude of 35,000 ft. and Mach number of 0.8. The maneuvers performed will be predetermined pitch, roll and yaw maneuvers. These maneuvers will be completed by a “pilot” using a joystick to make control inputs with the aircraft utilizing a feedback control law, and with the aircraft in open loop configuration – no augmentation whatsoever. The student will also have a hard coded computer pilot perform these maneuvers to maintain consistency. The first step in creating the control law was placing the CL poles. The initial poles would then be placed in a K matrix; the pole values are listed in

The figures for the flights were taken directly from the Simulink output plots. As can be noted the aircraft performed significantly better with the control law than without. No points were obtainable in the OL flights, while full points were awarded in the FB flights – both piloted and computer controlled.This project reiterated the understanding of how performance is changes with active control solutions as opposed to costly, and time intensive conventional solutions. The Convair 880 with no feedback control law could not achieve even adequate scores on the maneuvers, while with the control law, the aircraft had no troubles achieving desired results consistently, with human and computer
Review the FAA’s regulations (FARs) regarding duty day limits for FAR Part 121, Part 135, and Part 91 flight operations. Next, analyze and evaluate the differences in the regulations between Parts by creatively applying the concepts of human performance and limitations that you learned in this module. Finally, develop and support your opinion as to whether the differences in the regulations are justified in regard to maintaining aviation safety. As always, support your work with a reliable source(s).
World War was had been the first major conflict that saw use of the newly invented airplane. Newspapers filled with stories of daring pilots, valiantly taking down the opposing Luftwaffe. Ace became a term for a pilot who successfully shot down at least five enemy aircraft; however there were a special few pilots who far surpassed this and went down in history as the top aces. America’s “Ace of Aces” was Eddie Rickenbacker who throughout the war won twenty-six aerial victories, and earned the Medal of Honor for taking on seven German planes by himself, downing two (Sherman). Coming in second was Frank Luke Jr. with 14 enemy balloons and four enemy planes. He was known as the “Arizona Balloon Buster” and was posthumously awarded the Medal of Honor for his last victory, when he shot down three balloons while taking fire from eight planes, then, as he was going down, he opened fire on German ground troops killing six, and finally, when asked to surrender, he instead
Microsoft does not always get it right, but Microsoft Flight Simulator is the one product where developers have received almost unanimous praise from gamers and critics alike. A much improved follow-up to Flight Simulator 2004, Simulator X has better graphics, better presentation and higher level of replayability. In fact, Microsoft Flight Simulator comes close to the real experience of flying, but you should be aware that the download size is a bit big at 636.2 MB. It takes around five minutes to install, and then you will have three choices. You can do an introductory test flight, drop flour on targets or do a Caribbean Landing. Dropping flour takes practice while the other two options hone your experience with the controls and help you to master the landing.
As humans, one major phenomenon that we have been able to learn about is the mastery of flight. Without the discovery of flight, airplanes would be a pipe dream! There are about 4 major forces that play into affecting how flight works. In this research paper we will discuss all of the concepts that allow this complex process to take place. The first force that we will discuss is one known as weight.
Abstract: Throughout history, human beings have been astonished by the concept of flight. In the modern world, planes, helicopters and other aircrafts have been engineered to fulfil this perception, allowing people to travel around the world in easy. However, just like cars and trains, planes are also prone to accidents influenced by bad weather conditions. The information below describes how a thunderstorm and wind shear affected Delta fight 191 in 1985. Which will provide the physics behind the accident and the weather system and create recommendations to help limit these types of air accidents. Introduction/ background: The concept of flight follows basic physics principles includes Bernoulli's principle, forces in flight and how the motion

With the increase in air traffic, new laws are regulating the ways for pilots to react to particular situations. These rules are based on those that Europe has developed for aircraft established on scientific positions. For instance, if one aircraft is to approach another in a face-to-face meeting, both pilots are to steer their aircraft right while maintaining a distance of at least 100 yards away from each other. In addition to that, an aircraft cannot remain above or below another for extended periods of time, nor can they fly above a city or town unless needed. Another such rule establishes that a zeppelin must add 600 yards of clearance in any situation. These laws have considered the massive size and speed of aircraft in order to provide
An aircraft operating manual provides climb, cruise, and descent fuel burn graphs based on standard day atmospheric conditions. The calculator is required for basic math equations to find the performance data for today’s weather conditions. Arithmetic used to solve our aircraft performance can take another thirty minutes to complete depending on how proficient the user is.
The 20th century was an amazing period of technological advancement. It progressed from horse and buggies to moon landings, multi-megaton hydrogen bombs, and jet aircraft like the SR-71 that flew so fast (mach 3) and high (80,000 feet) that even missiles couldn't come close to knocking it out of the sky.
In this short essay I will discuss an incident of the Ariane 5 rocket where it failed on its first flight. The problem was a programming issue where not everything was accounted for properly. I will now explain the general circumstances that lead to the explosion of the Ariane 5 rocket.
The theories behind how an aircraft flies are still, too this day, highly debated as the aviation community is unable settle on one sole idea. The best way too try and describe the principles of flight is by incorporating a few of the theories together and then applying them to the shape of modern aviation aerofoils (the cross-section of an aircraft wing). To develop some basic understanding of how an aircraft flies, we should look at the four forces which act upon an aircraft in steady flight and they are shown in Figure 1.
A pilot’s career doesn’t just start up as soon as he takes the license, but it’s a start of a long way that would be accompanied with technological advancements and multiple trainings to be on top of things since its well known that a high percentage of accidents are usually human based. Training pilots is one factor that has to be balanced by decision-making skills such as a great pilot judgment. The issue of pilot decision making has a great impact on the safety of aviation, hence our aim here is to help the pilot’s in improving their decision making skills in accordance with mitigating risks that accompany each flight.
Plane crashes occur for a number of reasons. There seems to be a consensus with the general public that flying is dangerous, engines fail and planes crash. That is true some times, although the majority of plane crashes occur largely due to a combination of human error and mechanical failure. In much of aviations accidents mechanical failure has been a contributing factor. It is impossible however to blame plane crashes on one reason since events leading up to an accident are so varied. Reasoning for plane crashes can be placed in a broad number of categories.
The helicopter pilots, in general, are required to be skillful in operations on both improved and unimproved surfaces. During normal or slope takeoffs and landings with some degree of bank angle or side drift with one skid or wheel on the ground causes the helicopter to roll. When the rollover happens, the lateral cyclic control response becomes more sluggish and less effective than for a hovering helicopter. Consequently, if a roll rate is permitted to develop, a critical bank angle may be reached where roll cannot be corrected, even with full lateral cyclic, and the helicopter will roll over onto its side. As the roll rate increases, the angle at which recovery is still possible is significantly reduced. The critical rollover angle is also reduced. So, the goal of this essay is to cover the factors influencing dynamic control such as solo flight, cross wind, tail rotor thrust etc. and understand the recognition of dynamic rollover, how to avoid it and steps required for recovery. In addition, the effects of critical rollover angle on dynamic rollover and factors influencing dynamic rollover are also discussed.
Mechanical and hydro mechanical flight controls system comprise of all heavy steel cables, metallic pipes with hydraulic fluid, cables and pulleys which adds to the air craft total weight thus slowing it down and decreasing its full efficiency. Both systems frequently need unnecessary backup to tackle mechanical failures, which further increases weight. Additionally, both have inadequate capability to adjust to changing aerodynamic conditions. Dangerous maneuverability such as stalling, spinning and pilot-induced oscillation (PIO), which is dependent chiefly on the strength and configuration of the aircraft concerned rather than the control system itself, can still occur with these systems (Crane 2002).
