Heat generation in aircraft tires under free rolling conditions

A method was developed for calculating the internal temperature distribution in an aircraft tire while free rolling under load. The method uses an approximate stress analysis of each point in the tire as it rolls through the contact patch, and from this stress change the mechanical work done on each volume element may be obtained and converted into a heat release rate through a knowledge of material characteristics. The tire cross-section is then considered as a body with internal heat generation, and the diffusion equation is solved numerically with appropriate boundary conditions of the wheel and runway surface. Comparison with data obtained with buried thermocouples in tires shows good agreement

Two-stage chain sampling inspection plan

A comparison of some static and dynamic mechanical properties of 18 x 5.5 and 49 x 17 type 7 aircraft tires as measured by three test facilities

The properties were measured during static, slow rolling, and high-speed tests, and comparisons were made between data as acquired on indoor drum dynamometers and on an outdoor test track. In addition, mechanical properties were also obtained from scale model tires and compared with corresponding properties from full-size tires. While the tests covered a wide range of tire properties, results seem to indicate that speed effects are not large, scale models may be used for obtaining some but not all tire properties, and that predictive equations developed in NASA TR R-64 are still useful in estimating most mechanical properties

Goal Setting and Choice on Student Motivation

The purpose of this research is to determine what effect weekly conferences and goal setting opportunities have on the motivation of kindergarten children, in a multi-age (3-6 year-old) Montessori early childhood classroom in the Midwest. The goal was for children to become selfmotivated to choose and practice independent work that is developmentally appropriate. Data was collected before, during, and after the project using an observational checklist to determine the effectiveness of implementing goal setting and conferences with students. The research showed that writing goals in a journal was helpful for the majority of students. The students involved in the study came into the classroom ready to choose the lessons that were written in their journal. Also witnessed was an increase in positive talk and encouragement throughout the classroom. The students were reassuring each other and checked on one another to see how close they were to meeting their goals. Future research could be done to determine if goal setting could be carried over into the home and further research into intrinsic motivation of children would be helpful

Definition of Tire Properties Required for Landing System Analysis

The data bank constructed provided two basic advantages for the user of aircraft tire information. First, computerization of the data bank allowed mechanical property data to be stored, corrected, updated, and revised quickly and easily as more reliable tests and measurements were carried out. Secondly, the format of the book which can be printed from the computerized data bank can be easily adjusted to suit the needs of the users without the great expense normally associated with reprinting and editing books set by ordinary typography

Developing Men/Fathers As Spiritual Leaders In The Home In Kitsap County, Washington

Problem The Adventist church, along with most religious organizations today, struggles to develop a multigenerational faith vision and practice among its believers. Fewer Adventist youth and young adults appear to have an Adventist worldview or share the churches core values. They are often absent from general church life and worship. The research that has led to this project addresses men/fathers as being a primary solution in faith transmission and spiritual nurture of the next generation. Yet, the current vacancy of fathers in the homes and churches has created some of the greatest social needs in American society today. Literature is replete with information regarding the absence of men/fathers. However, literature is sparse on why men are absent from their roles both in the church and in the home. This project seeks to address the issues of why youth and young adults are leaving our churches by focusing on the spiritual role of men/fathers in the transmission of faith, core values and spiritual experience to their families. Method The task of this project is to develop a strategy to inspire, train, and empower men/fathers in Kitsap County, Washington to be the spiritual leaders in their home and church. The initial method employed was programmatic in nature, but it was soon abandoned in favor of a focused one-on-one approach. This second more personal approach proved more effective in inspiriting and nurturing men/fathers as a key leadership influence in the transmission of faith, core values, and spiritual experience to his family. Results The initial methodology utilizing programming as a key component in developing men/fathers as spiritual leaders has proven significantly less productive than did the one-on-one mentor/coaching that this project shifted towards. As a result, many men/fathers who experienced only the initial programming stage of this project missed altogether the individualized attention that has proven most effective in both inspiring and nurturing men as a spiritual leader in their homes. Each of the men/fathers who kept engaged long enough to experience the one-on-one focus, demonstrated improvement in both their personal and family’s spiritual growth. Conclusion This project led to four conclusions: a) a programmatic approach to nurturing or men/fathers proves ineffective; b) a personal one-on-one method evidences significant personal faith development and spiritual leadership vision on the part of men/fathers; c) Men/fathers need both factual information and continued one-on-one personal inspiration to make a life altering decision; d) all men/fathers need a mentor/coach to succeed in a spiritual transformation. There might be a few exceptions, however there is still an external driving factor in their lives (i.e. money, wife, friend, passion for something, learned discipline, etc.). The topic of developing men/fathers as positive spiritual leaders is not popular in the American culture. There is a general diminishing of the male role and identity as well as a negative portrayal of weak men/fathers and the problems they create especially in the home. Why? Why are men disinclined to be a spiritual leader in the home? Is there a unique natural tendency or personality in men to facilitate this condition? There are many ideas and timelines as to when man/fatherhood began to decline. Yet, few authors both religious and secular indicate a reason for the decline of men/fathers

3D Visualization of Coral Reef Habitat

A bathymetric survey was recently conducted in Southeast Florida (Broward County) during April 2001 using the Laser Airborne Depth Sounder (LADS) system. This four-meter resolution survey encompassed from North Dade County, through the length of Broward County coastline, to south Palm Beach County (approximately 43 km) and from the shore eastward to depths of approximately 40 m (2.5-3.5 km offshore). This georeferenced data was sun shaded at various angles and azimuths and draped with a NOAA NAPP 1:24,000 georeferenced air photograph mosaic. The model was zoomed and tipped to the desired orientations and processed into three-dimensional perspectives. Two views, slightly offset, were used to create anaglyphs. The anaglyph provided an actual three-dimensional view of the bathymetry. Multiple view options were useful for identifying benthic features including coral reefs and associated habitats
