Fundamental Sizing Implications Of Constant Or Increasing Weight Aircraft, Robert A. Mcdonald

Robert A. McDonald

As the energy storage capabilities of batteries and fuel cells advance, these technologies are increasingly being considered for aircraft primary propulsion. In addition to other fundamental differences from conventional systems, these concepts may have constant or even increasing mass throughout the mission. In this paper, the implications of constant or increasing mass on aircraft sizing are considered with the aim of generating insight for the design of these systems.

The North Dakota Space Robotics Program: Teaching Spacecraft Development Skills To Students Statewide With High Altitude Ballooning, Jeremy Straub, Ronald Fevig

Jeremy Straub

The University of North Dakota is serving as the lead institution in a statewide effort to develop student spacecraft engineering skills. This effort, which is part of the North Dakota Space Robotics Program (NDSRP), provides students the ability to participate in the design, development and fabrication of a small satellite analog that is launched by a high altitude balloon. The first iteration of the NDSRP Near-Spacecraft Project is generating a functional prototype of a remote sensing payload, which will perform onboard image processing. This project included undergraduate and graduate students from two institutions and five different academic departments. The students …

Formalizing Mission Analysis And Design Techniques For High Altitude Ballooning, Jeremy Straub, Ronald Fevig

Jeremy Straub

High altitude balloon (HAB) missions can be and are used to teach concepts related to spacecraft and satellite design. A HAB mission, however, presents unique characteristics, which must be understood and respected to produce a desirable outcome. Because of this, flying an unaltered satellite design as a HAB payload would be as undesirable as utilizing an unaltered HAB design as a satellite. A well-defined process for HAB mission design is thus needed. The process presented mirrors commonly used space mission design processes to facilitate easy transition between the two. It is also comparatively simple, due to the smaller scale of …

Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub

Jeremy Straub

A multi-tier, multi-craft mission architecture has been proposed but, despite its apparent promise, limited use and testing of the architecture has been conducted. This paper proposes and details a mission concept and its implementation for testing this architecture in the terrestrial environment. It is expected that this testing will allow significant refinement of the proposed architecture as well as providing data on its suitability for use in both terrestrial and extra-terrestrial applications. Logistical and technical challenges with this testing are discussed.

Aircraft Operations Based Mission Requirements, Robert A. Mcdonald

Robert A. McDonald

The mission capabilities of aircraft in the current commercial fleet are a combined result of many factors. The launch customer for each aircraft has a voice in determining the requirements. The manufacturer desires to best position the aircraft in the market considering their own aircraft and their competitors aircraft it will replace and compete with. Consequently, anyone considering the development of an aircraft to compete with or replace an aircraft in-service must do more than simply choose to meet the capabilities of that aircraft. This is especially true when unconventional systems are considered; the fundamental trade-offs for these systems may …

Real-Time Strategies For Enhancing Aircraft Performance In Wind, Kamran Turkoglu

Kamran Turkoglu

This thesis presents real-time guidance strategies for unmanned aerial vehicles (UAVs) that can be used to enhance their flight endurance by utilizing insitu measurements of wind speeds and wind gradients. In these strategies, periodic adjustments can be made in the airspeed and/or heading angle command for the UAV to minimize a projected power requirement at some future time. In this thesis, UAV flights are described by a three-dimensional dynamic point-mass model. A stochastic wind field model has been developed not only to reflect the mean wind magnitude behaviour in both vertical and horizontal axis, but also has it been extended …
