Material Vulnerabilities In Aviation: A Comparative Study Of Hiduminium Rr58 In The Concorde, Siddhant Singh, Kuldeep Agarwal Jan 2025

Material Vulnerabilities In Aviation: A Comparative Study Of Hiduminium Rr58 In The Concorde, Siddhant Singh, Kuldeep Agarwal

Automotive and Manufacturing Engineering Technology Department Publications

The catastrophic crash of Air France Flight 4590 in the year 2000 disclosed huge flaws in the material used to manufacture the Concorde fuel tanks, Hiduminium RR58 (Aluminum 2618A). Although this alloy was selected due to its resistance to high-temperature, this research examines its thermal and mechanical vulnerabilities, especially in relation to Aluminum 7075-T3, a large-scale application of which in the Boeing 747 was widespread. By comparing tensile strength, thermal conductivity, fatigue life, and creep life, this research determines how Hiduminium RR58's over-aging susceptibility, thermal cycling degradation, and rupture due to impact were contributory causes to the disaster. The study …

Nothing But A Number: A Closer Look At Stall Speed, Nihad E. Daidzic Mar 2020

Nothing But A Number: A Closer Look At Stall Speed, Nihad E. Daidzic

Aviation Department Publications

CFIS REPEAT IT LIKE A MANTRA: An airplane can stall at any airspeed, in any pitch attitude. Your trainer’s wing always stalls when it exceeds its critical angle of attack—and that can happen even if the airplane is pointed straight down and approaching VNE. So what do the stall speeds published in the pilot’s operating handbook mean? These only apply for the stated conditions: often level flight, maximum gross weight, and most forward center of gravity, with flaps retracted (VS1) or in the landing configuration (VS0). Factors such as total weight, load factor, power, and center of gravity location affect …

A New Model For Lifting Condensation Levels Estimation, Nihad E. Daidzic Jan 2019

A New Model For Lifting Condensation Levels Estimation, Nihad E. Daidzic

Aviation Department Publications

Knowledge of and the ability to predict lifting condensation levels (LCL) is important ingredient in weather predictions, cloud formation, planetary albedo and Earth’s energy balance. It is also essential topic in aviation safety and flight operations. In this article, we derive a new model of LCL and compare it to some older commonly-used models. This includes also the recently published Romps’ (2017) model. The new model presented here includes dependence, however weak, of the surface atmospheric pressure and the specific humidity on the LCL height and temperature. Such is not the case with widely used models and expressions by Espy …

Isolation And Onboarding: Gender Bias In Aviation Training Documents, William Hart Jan 2018

Isolation And Onboarding: Gender Bias In Aviation Training Documents, William Hart

Technical Communication Capstone Course

There is a growing interest in male-dominated industries and the challenges women face finding their place within the workplace community. Yet, there seems to be little research on how training documents, generally created by technical communicators, may isolate and limit women who seek to pursue careers in these fields. Technical communication and gender scholars have examined women in the technical communication field and gender bias in male-dominated industries but have not yet examined gender stereotypes in training documents. Training documents are designed to provide written instructions and a reference guide for job functions, workplace rules, orientation, and company policies. This …

Flight Dynamics: Flying Qualities Of Handling Factors Are Engineered Into The Aircraft Design, Nihad E. Daidzic Dec 2017

Flight Dynamics: Flying Qualities Of Handling Factors Are Engineered Into The Aircraft Design, Nihad E. Daidzic

Aviation Department Publications

Flight dynamics is an aerospace engineering discupline that addresses aircraft stability and controllability. It is also mathematically very intensive and is traditionally the most difficult in the pilot training curriculum. Ultimately, it does not matter how good steady-state performance of an aircraft design is if its flying (handling) qualities are deficient. Paradoxically, the first airplane Wright Flyer, was statically and dynamically unstable, had large control authority, and was difficult to fly. We've come a long way since those early days, but stability is still vitally important in aircraft design and flight ops. The focus of this article will be airplane …
