摘要

Nominal and optimal boost climb trajectories were developed for an air-launched vehicle. The agreement between approximate nominal and exact numerical solutions was quite good. Three payoffs were addressed for the optimal trajectories; maximum speeds at burnout or apogee, minimum fuel to apogee, and minimum time to apogee. The last two are equivalent since the fuel-burning rate was constant. Thrust vectoring was considered for one problem, but the difference relative to zero thrust vectoring was negligible. The remaining problems only considered zero thrust vectoring. In general, the optimal angle-of-attack decreased with increasing time. The change was greater for the minimum time solution. For this case, a fast pitch-up occurred initially and then the angle-of-attack rapidly decreased to the angle-of-attack for -C sub LMAX. The gave the fastest pitch over to apogee. The minimum time solution may reach apogee before burn-out. This never occurs for the maximum speed case; the terminal condition is reached at or after burn-out. (Author)

ABSTRACTudThe purpose of this research is to obtain an optimal formulations of Black mulberry leaves dried noodle product by using Design Expert Application with Design Mixture D-optimal method.udThis research was done with two phases. The preliminary procedures research is to determine levels of antioxidant activity, chlorophyll content, and the levels of tannin that was contained in black mulberry leaves, the black mulberry leaf flour, a pare fruits, and pare flour. Primary research is to determine the best formulation by using a Mixture Design Expert Design D-optimal method, for a purpose is to optimized the Black mulberry leaf dry noodle. Responses in this studies are a chemical analysis response by using a crude fiber analysis and protein analysis. Physical response is water absorption. Sensory response are color, flavor, and odor.udBlack mulberry leaves dried noodles was made from wheat flour, black mulberry leaf flour, and pare flour, other materials such as an eggs, water, salt, and sodium bicarbonate, of the 16 formulations that has offered to produce an optimal formulation based on desirability which contains 39.69 Flour,14.25 Black Mulberry Leaves flour, 3.06 Pare fruit and flour amounted, and other materials are 30 water, 10 eggs, 2 salt, and 1 sodium bicarbonate. The formulation has been result by program 11,05 crude fiber content, 12.93 protein, 274.31 water absorption, 4,31 for color attribute, 3,87 for taste attribute, and 3,71 for aroma attribute.ududKeyword: Black mulberry leaf dried noodles, optimization.
