From 1950 Australia’s Long Range Weapons Establishment took steps into an almost unknown future. Building on a tiny bit of experience John Ovenstone addressed a deepening problem with calculations and defined an automatic computing machine. Elliott Brothers used their electronics expertise and bent their efforts from developing their first commercial computer to fill Ovenstone’s order. As LRWE ...

The Rocket Engine Design Tool for Optimal Performance-2 (REDTOP-2) is a newly created engineering design tool for use in the conceptual and preliminary design of space transportation systems utilizing liquid propulsion rocket engines. REDTOP-2, one of many unique engineering tools commercially available from SpaceWorks Engineering, Inc. (SEI), represents a novel entry into the current suite of ...

We lured White Ibises (Eudocimus albus) to trap sites with decoy plastic flamingos and captured them with a rocket net or mist nets. Our ability to attract ibises to a site (and consequently our capture success) was affected by vegetation height and water depth but not by decoy numbers or their arrangement. Both the rocket net (37 ibises) and mist nets (97 ibises) caught birds. The number of bi...

Rocket fairings, load-carrying structures of solid rocket motor case, e.g., inter-stage joint, satellite-rocket joint, etc., usually take the shape of conical shell sections. This paper is to evaluate spatially distributed microscopic control characteristics of distributed actuator patches bonded on conical shell surfaces. The converse effect of piezoelectric materials has been recognized as on...
