Thermal Testing And Simulation Of Lunar And Martian Isru-Based Materials, Andres Campbell
Thermal Testing And Simulation Of Lunar And Martian Isru-Based Materials, Andres Campbell
All Undergraduate Theses and Capstone Projects
Upon the eventual return of humans to the lunar surface, leveraging local resources to construct landing pads and other infrastructure is an essential component to minimize cost and risk. The inability to accurately model landing and launch scenarios to predict damage to lunar structures poses risks to astronaut and equipment safety. The following experiment is an investigation of using simulation software and temperature sensors to model lunar and Martian regolith simulant-based concrete exposed to thermal loads. The basis of this experiment is built upon standards defined by the American Society for Testing and Materials, the fundamental axioms of structural health …

Nothing But A Number: A Closer Look At Stall Speed, Nihad E. Daidzic
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 …
Wind Tunnel Measurements And Data Analysis Tutorial, Nihad E. Daidzic
Wind Tunnel Measurements And Data Analysis Tutorial, Nihad E. Daidzic
Aviation Department Publications
This tutorial gives details on processing of raw aerodynamic data measured directly in the wind tunnel on airfoils and wings. Also procedures and equations from the lab report are given and demonstrated how to compute geometric characteristics of wings/airfoils and air data. All numeric results are typically rounded to five significant digits.

United States Patent, Patent Number US 10,202,204 B1, Date of Patent February 12, 2019.
A total runway safety system (TRSS) and method measures, monitors, manages, and informs flight crew on the progress of takeoffs and landings and of any hazardous runway conditions. In some embodiments, the TRSS measures, monitors, and informs flight crew of longitudinal and lateral runway tracks thus preventing overruns and veer-offs during takeoffs and landings. In some embodiments, backscatter of infrared laser beams emitted by the aircraft is used to evaluate groundspeed and the reflectivity of the runway surface to make estimates of the surface conditions, roughness …

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