Students Interested In Satellite Communications Can Gain An Edge In The Job Market By Studying Science And Theory, Ben Chang

Online Journal of Space Communication

The mind has an extraordinary ability to see things that are hoped for, Arthur C. Clarke said in 1973. Years later he noted that it cost about $100, in terms of kilowatt-hours, to go to the moon, "whereas it costs about a billion dollars the way we've done it."

These two quotes from the grandfather of satellite communications and author of 2001: A SPACE ODYSSEY point to one of the primary qualities INTELSAT looks for in filling engineering positions: the ability to apply book knowledge to the practical aspects of satellite communications.

Adaptive And Neural Network-Based Aircraft Tracking Control With Synthetic Jet Actuators, Joshua Teramae

Doctoral Dissertations and Master's Theses

Wing-embedded synthetic jet actuators (SJA) can be used to achieve maneuvering control in aircraft by delivering controllable airflow perturbations near the wing surface. Trajectory tracking control design for aircraft equipped with SJA is particularly challenging, since the controlling actuator itself has an uncertain dynamic model. These challenges necessitate advanced nonlinear control design methods to achieve desirable performance for SJA-based aircraft (e.g., micro air vehicles (MAVs)). In this research, adaptive and neural-network based control methods are investigated, which are specifically designed to compensate for the SJA dynamic model uncertainty and unpredictable operating conditions characters tic of real-world MAV applications. The control …

Intelligent Management Of Constrained Links For Distributed Autonomy, Troy R. Johnson, Nathan A. Jensen

Space Dynamics Laboratory Publications

This paper addresses one of the main underlying obstacles overlooked when adding autonomy to a cooperative cluster of nodes working together to complete global objectives. Whether these nodes are ground, sea, air, or space vehicles, a constrained link is used to distribute information between the vehicles. The limited bandwidth of the constrained link must be shared between all nodes and becomes a pinch point for distributed autonomy. Intelligently managing the shared information and controlling how it is replicated across all nodes is vital. Lack of communication results in poor team performance. Intermittent connectivity and delayed intelligence sharing leads to the …

Airplane Pitch Response To Rapid Configuration Change: Flight Test And Safety Assessment, Ralph Kimberlin, Markus Wilde, Brian Kish, Isaac Silver

Journal of Aviation Technology and Engineering

This paper examines airplane response to rapid flap extension on seven general aviation airplanes. The scenario involves a pilot flying in the traffic pattern becoming distracted, abruptly extending flaps while looking outside the airplane, and failing to notice airspeed and pitch-attitude changes. The airplanes tested reached pitch forces of up to 36 lbf, meeting FAA requirements but exceeding the capability of 55% of the population. Flight data showed a pitch-up to more than 30˚ in 5 s after flap extension, causing airspeed to drop below stall speed for four of the airplanes. At traffic pattern altitudes, stalling an airplane can …

Computational Aerodynamics Of A Wing Mounted Propeller, Sarah Agam

College of Engineering & Technology (Batten) Posters

Computational fluid dynamics (CFD) is a vital component in aerospace engineering. A major use of CFD is analyzing the flow properties to determine outputs like aerodynamic lift and drag over an airfoil or compute engine efficiency. It is more practical to conduct a CFD analysis first before doing experimental work as CFD allows for rapid and diverse testing of propeller shapes at a lower cost. CFD also allows for a wider range of testing parameters; for example, an airfoil can be subjected to steady, unsteady, incompressible, or high velocity flows.

Propellers are extensively used in the aircraft industry, especially in …

Coolant for both cooling arrangements is supplied using an array of impingement jets. Experimental data are provided for a mainstream Reynolds number Rems range of 168,000–181,000. Full-coverage film cooling initial blowing ratio values are 2.5, 3.2, 4.4, and 5.2, …

Determination Of The Feature Resolution Of Processed Image Data Via Statistical Analysis, Joseph S. Indeck, Jesus O. Mares Jr., James P. Vitarelli, Kavan Hazeli

PRC-Affiliated Research

A method is presented to determine the feature resolution of physically relevant metrics of data obtained from segmented image sets. The presented method determines the best-fit distribution curve of a dataset by analyzing a truncated portion of the data. An effective resolvable size for the metric of interest is established when including parts of the truncated dataset results in exceeding a specified error tolerance. As such, this method allows for the determination of the feature resolution regardless of the processing parameters or imaging instrumentation. Additionally, the number of missing objects that exist below the resolution of the instrumentation may be …
