Intermediate gel in crossed and in fused rocket immunoelectrophoresis.

Abstract: 0 tent of an unknown antiserum (Ab-x) with that of a reference antiserum (Ref-Ab), by using a reference antigen (Ref-Ag). The 2 antisera are compared by running 2 plates which are identical apart from the lack of Ab-x in the intermediate gel of the control plate. It is possible to compare the antibodies of Ab-x with those of Ref-Ab, but 'free' antigens, if present in Ab-x, will also be revealed if their corresponding antibodies are present in RefAb.

Burning of Nano-Aluminized Composite Rocket Propellants

Abstract: Several aluminum nanopowders were examined and compared with the final goal to evaluate their application in solid rocket propulsion. A detailed investigation of pre-burning properties by the Brunauer-Emmet-Teller method, electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy was carried out. Ballistic properties and the combustion mechanism of several aluminized propellant formulations were investigated. In particular, aggregation and agglomeration of metal particles at and near the burning surface were analyzed by high-speed high-resolution color digital video recordings. All tested nano-powders are of Russian production; their physical characterization was carried out at the Istituto Donegani (Novara, Italy); ballistic studies were performed at the Solid Propulsion Laboratory (Milano, Italy) using laboratory and, for comparison, industrial composite propellants based on ammonium perchlorate as an oxidizer. Results obtained under a fair variety of operating conditions typical of rocket propulsion indicate, for increasing nano-Al mass fraction or decreasing nano-Al size, larger steady burning rates with essentially the same pressure sensitivity. While aggregation and agglomeration phenomena still occur, their significance may be reduced by using nano-Al instead of micro-Al.

Aerothermodynamics of Gas Turbine and Rocket Propulsion

Abstract: This seminal book on gas turbine technology has been a bestseller since it was first published. It now includes a comprehensive set of software programs that complement the text with problems and design analyses. Software topics included are atmosphere programs, quasi-one-dimensional flow programs (ideal constant-area heat interaction, adiabatic constant-area flow with friction, rocket nozzle performance, normal shock waves, oblique shock waves), gas turbine programs (engine cycle analysis and engine off-design performance), and rocket combustion programs (Tc and PC given, He and PC given, isentropic expansion).
