Most externally carried aircraft stores are basically slender bodies. These stores are usually carried underneath the wings or fuselage (itself a slender body) and in many cases multiple bodies are carried in proximity. This proximity introduces new interaction forces, both in the longitudinal and lateral directions. Wind tunnel experiments on a pair of generic slender bodies-ellipsoids of a 6:1 slenderness ratio placed in parallel in the longitudinal direction, at various lateral spacing and axial displacement are described. The results show that significant side and axial forces are obtained. The results are then compared to calculations based on a theoretical model recently applied by the senior author to the interaction of pairs of such slender bodies, with very good agreement, up to the limits of the first order model. When the bodies are positioned correctly, the axial interaction force counters all of the viscous drag on one of the bodies.

A modular model, consisting of cruciform canard controls mounted on a thin forebody and five interchangeable thick (larger-diameter) main bodies, was tested at a Mach number of 0.8. The canards were installed at the + and x positions and at deflection angles of 0, 6, and 12 deg. The model was equipped with two sting balances in a setup that enabled the obtaining of loads acting on the canard unit and those acting on the main bodies. The aerodynamic characteristics of the bodies alone and those of the canard unit are analyzed and compared with databases and predictions, respectively. A small effect of the thickening of the main bodies on the canard unit is observed.

Prior work has reported mixed evidence for the gender gap in crime concern and crime responses, yet very few studies have considered the importance of the framing of a crime in explaining this gap. Crime frames are important because they can raise deep levels of concern that activate a criminal justice system response to the crime. This study draws on the literature on problem framing to examine gender differences in crime concern and crime responses in relation to human trafficking. Human trafficking is a type of crime that has raised public alarm in the U.S and is being framed by the government and the media as a crime to which women are at increased risk. Using data from a national probability sample of approximately 2000 Americans, the findings show that beliefs about the causes of human trafficking, specifically gender discrimination and transnational crime, are associated with gender differences in concern and activation of the criminal justice system. These findings can guide future research on gender differences in crime concern and crime responses and call for research and policies that are sensitive to gendered effects of framing on public opinion about crime and criminal justice issues.
