The ability to use flight data to determine an aircraft model with structural dynamic effects suitable for piloted simulation. and handling qualities analysis has been developed. This technique was demonstrated using SR-71 flight test data. For the SR-71 aircraft, the most significant structural response is the longitudinal first-bending mode. This mode was modeled as a second-order system, and the other higher order modes were modeled as a time delay. The distribution of the modal response at various fuselage locations was developed using a uniform beam solution, which can be calibrated using flight data. This approach was compared to the mode shape obtained from the ground vibration test, and the general form of the uniform beam solution was found to be a good representation of the mode shape in the areas of interest. To calibrate the solution, pitch-rate and normal-acceleration instrumentation is required for at least two locations. With the resulting structural model incorporated into the simulation, a good representation of the flight characteristics was provided for handling qualities analysis and piloted simulation.

2Stories the Iroquois Tell Their Children

By Mabel Powers

Stories the Iroquois Tell Their Children by Mabel Powers is a beautiful collection of traditional Iroquois tales that not only entertain but also teach fundamental cultural values and life lessons. These stories, passed down through generations by elders around the fire, serve to educate children on themes such as bravery, kindness, respect for nature, and the importance of community. The book’s tales feature a range of characters including the Little People, animals, and children. Each story is rich with symbolic meaning. Powers also touches on the role of nature in these stories, reflecting the Iroquois' deep reverence for the natural world and its creatures, while exploring concepts like gratitude, generosity, and cooperation. By weaving together these ancient tales with lessons about life, the book offers not only a glimpse into Iroquois culture but also timeless wisdom that transcends generations. - Summary by Anthony Karl Futterer
