An integrated Rotorcraft Avionics/Controls Architecture to support advanced controls and low-altitude guidance flight research

Salient design features of a new NASA/Army research rotorcraft--the Rotorcraft-Aircrew Systems Concepts Airborne Laboratory (RASCAL) are described. Using a UH-60A Black Hawk helicopter as a baseline vehicle, the RASCAL will be a flying laboratory capable of supporting the research requirements of major NASA and Army guidance, control, and display research programs. The paper describes the research facility requirements of these programs together with other critical constraints on the design of the research system. Research program schedules demand a phased development approach, wherein specific research capability milestones are met and flight research projects are flown throughout the complete development cycle of the RASCAL. This development approach is summarized, and selected features of the research system are described. The research system includes a real-time obstacle detection and avoidance system which will generate low-altitude guidance commands to the pilot on a wide field-of-view, color helmet-mounted display and a full-authority, programmable, fault-tolerant/fail-safe, fly-by-wire flight control system

Preliminary design features of the RASCAL: A NASA /Army rotorcraft in-flight simulator

Salient design features of a new NASA/Army research rotorcraft - the Rotorcraft-Aircrew Systems Concepts Airborne Laboratory (RASCAL) - are described. Using a UH-60A Black Hawk helicopter as a baseline vehicle, the RASCAL will be a flying laboratory capable of supporting the research requirements of major NASA and Army guidance, control, and display research programs. The paper describes the research facility requirements of these programs together with other critical constraints on the design of the research system, including safety-of-flight. Research program schedules demand a phased development approach, wherein specific research capability milestones are met and flight research projects are flown throughout the complete development cycle of the RASCAL. This development approach is summarized, and selected features of the research system are described. The research system includes a full-authority, programmable, fault-tolerant/fail-safe, fly-by-wire flight control system and a real-time obstacle detection and avoidance system which will generate low-altitude guidance commands to the pilot on a wide field-of-view, color helmet-mounted display

Reclaiming the child left behind: the case for corporate cultural responsibility

Although a reasonable understanding of corporate social responsibility (CSR) exists, one dimension remains largely ignored. That is, the cultural impacts of corporations, or the bearing, at various levels of their business models, activities, and outcomes on the value systems and enduring beliefs of affected people. We introduce the notion of corporate cultural responsibility (CCR). The way corporations address CCR concerns can be reflected according to three stances: cultural destructiveness, cultural carelessness, and cultural prowess. Taken sequentially, they reflect a growing comprehension and increasingly active consideration of CCR concerns by corporations. In turn, we explicitly address issues related to the complex question of determining the cultural responsibilities of corporate actors; specify key CCR-related conceptualizations; and lay a foundation for discussions, debates, and research efforts centered on CCR concerns and rationales

Capturing Racism: An analysis of racial projects within the Lisa Simpson vs. University of Colorado football rape case

The spectacle of collegiate sports is the face of the American university. Collegiate sports are, as Hartman would put it, contested racial terrain. In America, sport incidents of sexual assault push the contested racial terrain into high relief. Such is the case with the Lisa Simpson versus the University of Colorado sexual assault case. This analysis of court documents, public comments and participant observation from the position of an expert witness reveals how racism is practised by powerful whites within and around a collegiate sport organization. Data collected at a moment of institutional crisis suggest that powerful university officials, acting on behalf of the university, appropriate \u27progressive\u27 concerns such as \u27hostile community\u27 and \u27the myth of the black rapist\u27 to draw attention to whiteness. This seemingly oppositional stance insulates the university and its athletic programme from charges of racial exploitation. These comments are contrasted with the testimony and actions of people of colour working within the athletic department. The essay concludes by arguing that as contemporary scholars\u27 concern with making whiteness visible enters popular culture, American sport fans will engage in racial discourse but in a way that will perpetuate racial inequality
