Fuel Leak Detection on Large Transport Airplanes

Data-Based Detection of Potential Terrorist Attacks on Airplanes

Statistical algorithms have been developed to detect unusual events or aberrations that may indicate serious problems; e.g., high incidence of infectious diseases (possible epidemics), excessive charges on a credit card or telephone (possible stolen card), or random operations on a computer (attack by a virus). Similar algorithms can be developed to detect unusual combinations of characteristic...

Leak detection

This paper will give an introduction to the leak detection of vacuum systems. Various methods to detect leaks as well as the most widely used helium leak detectors and their different applications are presented. Practical examples in the context of accelerator vacuum systems will illustrate the topic.

Measured Engine Installation Effects of Four Civil Transport Airplanes

INTRODUCTION The Federal Aviation Administration's Integrated Noise Model (INM) is one of the primary tools for land use planning around airports [1]. The INM currently calculates airplane noise lateral attenuation using the methods contained in the Society of Automotive Engineer's Aerospace Information Report No. 1751 (SAE AIR 1751) [2]. Researchers have noted that improved lateral attenuation...

Pipeline Leak Detection Techniques

Leak detection systems range from simple, visual line walking and checking ones to complex arrangements of hard-ware and software. No one method is universally applicable and operating requirements dictate which method is the most cost effective. The aim of the paper is to review the basic techniques of leak detection that are currently in use. The advantages and disadvantages of each method ar...
