Effect of ELEVON gap configurations on the longitudinal stability and control effectiveness of the 43-0 space shuttle orbiter (OA118)

Experimental aerodynamic investigations were conducted on a stingmounted 0.0405-scale representation of the 140A/B space shuttle orbiter in a 7.75 by 11-Foot low speed wind tunnel from April 24 to April 26, 1974. Differential inboard/outboard elevon panel deflections with the 6-inch gap were investigated to determine outboard panel aileron effectiveness. The elevons were deflected from +20 degrees to -40 degrees in various combinations. Aerodynamic force and moment data for the orbiter were measured in the body axis system by an internally mounted, six-component strain gage balance. The model was sting mounted with the center of rotation located at F.S. 60.172. The angle of attack range was from -10 degrees to +24 degrees

Investigation of space shuttle orbiter subsonic stability and control characteristics in the NAAL low speed wind tunnel (0A62b), volume 1

Experimental aerodynamic investigations were conducted on a sting-mounted 0.0405 scale representation of the 140A/B space shuttle orbiter in a 7.75 ft by 11 ft low speed wind tunnel during the time period from November 14, 1973, to December 6, 1973, with the primary test objectives being to establish basic longitudinal stability characteristics in and out of ground effect, as well as lateral-directional stability characteristics in free air. Two dual podded nacelle configurations were also tested, one with three dual podded nacelles on the lower wing surface, and the other with a single dual nacelle on the lower centerline with dual nacelle pylons mounted above each wing. Stability and control characteristics were investigated at nominal elevon, rudder, aileron, and body flap deflections. Pressure bugs were used to determine pressures on the vertical tail at spanwise stations, and aerodynamic force and moment data were measured in the stability axis system by an internally mounted, six component strain gage balance

Investigation of space shuttle orbiter subsonic stability and control characteristics in the NAAL low speed wind tunnel (OA62B), volume 2

Experimental aerodynamic investigations were conducted on a sting-mounted 0.0405 scale representation of the 140A/B space shuttle orbiter in a 7.75 ft by 11 ft low speed wind tunnel during the period from November 14, 1973 to December 6, 1973. Establishment of basic longitudinal stability characteristics in and out of ground effect, and the establishment of lateral-directional stability characteristics in free air were the primary test objectives. The following effects and configurations were tested: (1) two dual podded nacelle configurations; (2) stability and control characteristics at nominal elevon deflections, rudder deflections, airleron deflections, rudder flare angles, and body flap deflections; (3) effects of various elevon and elevon/fuselage gaps on longitudinal stability and control; (4) pressures on the vertical tail at spanwise stations using pressure bugs; (5) aerodynamic force and moment data measured in the stability axis system by an internally mounted, six-component strain gage balance.

Effects of the six engine air breathing propulsion system on space shuttle orbiter subsonic stability and control characteristics

Experimental aerodynamic investigations were conducted on a 0.0405 scale representation of the -89B space shuttle orbiter in the 7.75 x 11.00 foot low speed wind tunnel during the time period September 4 - 14, 1973. The primary test objective was to optimize the air breathing propulsion system nacelle cowl-inlet design and to determine the aerodynamic effects of this design on the orbiter stability and control characteristics. Nacelle cowl-inlet optimization was determined from total pressure - static pressure measurements obtained from pressure rakes located in the left hand nacelle pod at the engine face station. After the optimum cow-inlet design, consisting of a 7 deg cowl lip angle, short cowl, 7 deg short diverter, and a nacelle toe-in angle of 5 deg was selected, the aerodynamic effects of various locations of this design were investigated. The 3 pod - 6 Nacelle configuration was tested both underwing and overwing in three different longitudinal locations. Orbiter control effectiveness, both with and without Nacelles, was investigated at elevon deflections of 0 deg, -10 deg and +15 deg and at aileron deflections of 0 deg and +10 deg about 0 deg elevon

Re-theorizing the “Structure–Agency” Relationship: Figurational Theory, Organizational Change and the Gaelic Athletic Association

This article illustrates how the figurational sociology associated with Norbert Elias provides an alternative theoretical framework for explaining the relationship between, ‘individualorganization- society’ and organizational change, and in so doing transverses what is conceived as a false dichotomy between structure and agency. Through an historical case study of the Gaelic Athletic Association in Ireland, the ‘individual-organization-society’ relationship is conceptualized as overlapping figurations and organizational change is explained as figurational dynamics—the shifting social interdependencies between the individuals and groups comprising an organization, between that organization and other organizations, between social groups on a higher level of integration and competition. In tandem with this, the article illustrates how changes in the sources of power and identity are connected with these figurational dynamics

Snobbery and the triumph of bourgeois values: a speculative analysis of implications for hospitality

This is a ‘small’ paper that offers a broad-brush view of the nature of bourgeois values and implications of the same for our understanding of certain aspects of hospitality. The argument is speculative, but assertive. Bourgeois values, it is suggested, are inevitably snobbish in nature and designed to both construct and maintain largely irrelevant ‘cultural’ differences between and within social classes. This generation of difference is integrally consistent with the capitalist mode of production, facilitating the creation of demand for essentially artificial needs and wants. In the context of hospitality, bourgeois values sustain a language of hierarchy that simultaneously creates a culture of aspiration while allowing enterprises to extract optimum economic value from carefully segmented markets

‘Trust me I am a Football Agent’. The discursive practices of the players’ agents in (un)professional football

While the public and media attention is largely focused on the corruption scandals of high-ranking officials in international football, FIFA’s decision in April 2015 to deregulate football agents raises further concerns about its ability for self-regulation and governance. FIFA’s introduction (2006) and subsequent updating (2008, 2015) of its regulations and legal frameworks governing the activity of agents in professional football has important implications on the inner workings of international football. In this regard, FIFA’s decision to deregulate the industry is perhaps a reflection of the neoliberal influences surrounding the organisation to let the agents govern themselves and deal with the wrongdoings of the alleged bribery, exploitation and trafficking of young players. However, the deregulation of agents by FIFA can also be seen as the organisation’s inefficiency to maintain the primacy of self-regulation and self-governance in serious matters of the industry, such as agents’ global leadership and regulation of practices. This paper, using qualitative data collected from players, agents and managers from professional football leagues in the UK and Ireland, aims to uncover the unethical, extremely complex and deceptive sides of the agents’ industry. By doing so, it aims to emphasise the need for gold standards of practice and leadership in the regulation of international football, which desperately needs to restore its integrity. Two key issues are unpacked: (i) the alleged (un)ethical behaviour of football agents that provokes so much hostility in the football world; (ii) the power shift(s) from clubs and managers to agents and players and the implications these may have on the ethics of the business practices in football
