Steve Ainsworth’s follow-on to Vertical Trajectory Systems, this booklet goes over the physics of rocket flight and how, analytically, to optimize it for maximum altitude. While calculus is not involved, an understanding of Newtonian mechanics at the high school physics level is required to make the best use of the material here. As with Vertical Trajectory Systems, this is not a book for beginners! It will, however, provide an excellent reference for rocketeers as they expand their knowledge in the hobby.

"The purpose of this study was to test the effects on distance runners of living high, 1,780 m to 2,805 m and training low, 1,250 m, (LHTL) and how they would respond to living at different altitudes. The subjects were tested by running a sea level 3000 m time trial and completing a VO2 max test before and after a 28 day stay at altitude. Distance runners, (N=24, m=16, f=8) were recruited from high-school, collegiate and club teams across the country. All athletes completed the testing. Prior to traveling to altitude the participants were tested twice running 3000 m on the track and did VO2 max peak tests . The best results from both tests were used to create a baseline effort. They then lived at altitude (1,780, 2,085, 2,454 & 2,805 m) for 28 days. Once or twice a week at altitude participants would do interval training at low altitude, 1,250 m. In addition, they also trained by doing long slow distance at altitude. Upon returning to sea level they completed two more 3000 m time trials and two more V02 peak test. A paired samples t- test was used to determine differences between pre and post efforts and differences within the separate altitude groups. The LHTL method did show a significant difference (t=4.515, p=.0001) in the pre and post altitude 3000 meter time trials for the entire group. Within the total group there appeared to be differences between training conditioning before starting the study, so a second analysis was run separating them into a conditioned and de-conditioned group. Only the de-conditioned group showed significant improvements (t=8.411, p=.0001) pre to post. Within the altitude subsets there were also significant differences for the 2,085 m group in their time trial (t=3.610, p=.015) and the absolute VO2 peak test (t=-2.748, p=.040) . Both the 2,454 m and 2,805 m groups had significant difference in both their absolute (8000- t= -4.199, p=.009, 9000- t= -3.887, p=.012) and relative (8000- t= -3.026, p=.029, 9000- t= -3.478, p=.018) VO2 peak test. There was no significant difference in pre and post altitude 3000 meter time trials for any of the four altitude levels when separating into groups . In summary, the results of this study would suggest that the use of the LHTL method is an effective way for endurance athletes to improve their performance. It would appear that the best altitude level would be between 2,085 m and 2,454 m for the LHTL model"--Document.

These Proceedings provide valuable information on the exchange of ideas between scientists who apply nonlinear programming and optimization to real world control problems and those who develop new methods, algorithms and software. The papers deal with windshear problems, optimization of aircraft and spacecraft trajectories, optimal control for robots, the optimization of urban traffic control, general mechanical systems, multilevel inventory systems and robust control.
