PurposeThe purpose of this paper is to optimize the downrange for hypersonic
boost‐glide (HBG) missile under near‐real condition, and to validate the
suitability of proposed wall cooling materials.Design/methodology/approachThe
trajectory optimization problem is characterized by a boost phase followed by a
glide phase. A multi‐phase trajectory optimization tool is adopted to optimize
the downrange... hiện toàn bộ
The mechanism of stress formation in glass under‐going conditions of rapid
cooling, and the factors affecting the properties of the toughened glass
produced are discussed. The application of techniques for measuring the
temperature of glass, to the control and study of the toughening process are
described.
PurposeThe purpose of this paper is to apply a factorization‐based control
system design procedure to design of auto‐pilot
systems.Design/methodology/approachThe design approach is based on a previously
developed factorization‐based control system design procedure. The design
approach requires a stable coprime factorization of the plant, a set of stable
coprime factors that are solutions to the Be... hiện toàn bộ

Hamilton Standard dates back to 1919 when the Standard Steel Propeller Company
was formed in Pittsburgh, Pa. Standard Steel is best known for the propeller it
designed and built for Charles Lindbergh's Spirit of St. Louis.
