The purpose for the project is to test and demonstrate new technologies the Air Force would be interested in for research and development. The primary mission of KnightSat is to show how a constellation of satellites can maintain relative position with each other autonomously using the Microwave Electro Thermal (MET) thruster. The secondary mission is to use multiple satellite imagery to obtain 3 dimensional stereo photographs of observable terrain. Formation flying itself has many possible uses for future applications. Selected missions that require imaging or data collection can be more economically accomplished using smaller multiple satellites. The MET thruster is a very efficient, but low thrust alternative that can provide thrust for a very long time, hence provide the low thrust necessary to maintain the satellites at a constant separation. The challenge is to design a working control algorithm to provide the desired output data to be used to command the MET thrusters. The satellites are to maintain a constant relative distance from each other, and use the least amount of fuel possible. If one satellite runs out of fuel before the other, it would render the constellation less useful or useless. Hence, the satellites must use the same amount of fuel in order to maintain an optimal operational duration on orbit.

The opportunity to enhance the sense of fulfillment necessary in revolutionizing and liberating a person's daily life, regardless of their age, can be found in the manifestation of play. It is through the acknowledgment of instinct, nature, and discovery that play reveals its power. As a Theatre for the Very Young (TVY) practitioner, I utilize creative play to inspire exploration and innovation among students under the age of six.

Show moreThe opportunity to enhance the sense of fulfillment necessary in revolutionizing and liberating a person's daily life, regardless of their age, can be found in the manifestation of play. It is through the acknowledgment of instinct, nature, and discovery that play reveals its power. As a Theatre for the Very Young (TVY) practitioner, I utilize creative play to inspire exploration and innovation among students under the age of six. However, what are the ways in which theatre, specifically TVY, invites all generations of people to experience the power of play? This thesis documents the three-year development of When Pigs Fly, an original TVY experience that encourages audience members of all ages to engage in creative play through sensation, fellowship and discovery. This study explores the collective creation of When Pigs Fly as developed through research, education, and practice. In highlighting the cognitive and emotional benefits of creative play, this study seeks to legitimize TVY as a valued art form, and invites theatre-makers to utilize the research and practice shared to inspire future endeavors that will shape the outlook of TVY throughout the United States.

- Title
- Equivalency Analysis of Sidestick Controller Modes During Manual Flight.

- Abstract / Description

Equivalency analysis is a statistical procedure that can enhance the findings of an analysis of variance in the case when non-significant differences are identified. The demonstration of functional equivalence or the absence of practical differences is useful to designers introducing new technologies to the flight deck. Proving functional equivalence is an effective means to justify the implementation of new technologies that must be (")the same or better(") than previous technology. This...
Show moreEquivalency analysis is a statistical procedure that can enhance the findings of an analysis of variance in the case when non-significant differences are identified. The demonstration of functional equivalence or the absence of practical differences is useful to designers introducing new technologies to the flight deck. Proving functional equivalence is an effective means to justify the implementation of new technologies that must be (")the same or better(") than previous technology. This study examines the functional equivalency of three operational modes of a new active control sidestick during normal operations while performing manual piloting tasks. Data from a between-subjects, repeated-measures simulator test was analyzed using analysis of variance and equivalency analysis. Ten pilots participated in the simulator test which was conducted in a fixed-base, business jet simulator. Pilots performed maneuvers such as climbing and descending turns and ILS approaches using three sidestick modes: active, unlinked, and passive. RMS error for airspeed, flight path angle, and bank angle were measured in addition to touchdown points on the runway relative to centerline and runway threshold. Results indicate that the three operational modes are functionally equivalent when performing climbing and descending turns. Active and unlinked modes were found to be functionally equivalent when flying an ILS approach, but the passive mode, by a small margin, was not found to be functionally equivalent.
