Travel by air with long hours will create discomfort feeling for aircraft passenger especially economy class aircraft passenger. Long hour air travel will create physiological stress on aircraft passenger. It may due to seat space limitation, noise, vibration, cabin humidity as well as seat comfort. Seat comfort is a subjective feeling that related to psychological aspect of aircraft passenger....

Doppler velocity measurements from airborne meteorological Doppler radars require removal of the aircraft motion contribution in order to provide radial velocity of hydrometeor targets. This is a critical step for hydrometeor motion and wind retrievals. The aircraft motion contribution is defined as the scalar product between the radar antenna beam-pointing vector and the aircraft velocity vect...

Changes in aviation over the last 30 years have dramatically affected the way that flight crews fly aircraft. The implementation and evolution of the glass cockpit, however, has happened in an almost ad hoc fashion, meaning that it does not always properly support the flight crew in carrying out their tasks. In such situations, the crew's mental model of what is happening does not always match ...

Over the last century chemical propellants have been the dominant fuel source for the aviation and aerospace industry, primarily because they are able to provide ample power for a limited cost. However, over the last decade as the price of chemical propellant continues to soar and their detrimental effect on our environment comes to light, there has been a surge to develop an alternative propul...

The focus of ElectronixTutor is to build an intelligent tutoring system technology for Navy-relevant applications in training. The goal is to have an ITS for Apprentice Technician Training (ATT) courses in electronics for naval trainees who have completed boot camp and are in the process of A-school training under the Navy Educational Training Command and to supplement the human instruction wit...

A computer-based mathematical model is developed fqr the estimation of assessment of damage inflicted on an aircraft due to a ground-h,lscd air dcfcnce gun. It is assllmcd that thc aircraft is approaching thc targct from an arbitrary dircction and docs not changc it's trajectory during gun firing. Dimension of aircraft and trajcctory of warhead are assumed to be known. Damage to aircraft is cau...

Traditional commercial aircraft design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight. From the point of view of an aircraft manufacturer, however, this method does not guarantee the financial viability of an aircraft program. A better design approach would take into account not only aircraft performance but also factors such as aircraf...

This study analysed the performance of constant time based airborne spacing under different operational conditions using fast time simulation. The effects of time based spacing criteria, mixed aircraft types and wind conditions on the ability of an aircraft to maintain a time spacing behind a descending lead aircraft were investigated. The spacing performance of a previously used approximate ti...

This paper aims at describing how to design for human factors in the technology-intensive domain of fighter aircraft. Similar to space industry, the fighter aircraft industry has to manage technology-intensive development where the end user often has implicit or explicit human factors requirements or expectations that has to be managed though design. This paper describes the specifics of the do...

Aircraft performance enhancement by integrating the propulsion control system with the primary flight control system is demonstrated through two nonlinear flight control design examples. In the first example, high performance aircraft turning performance improvement using engine thrust modulation is demonstrated. In the second example, the flight propulsion system integration is used to achieve...
