Treatment of battlefield trauma presents a unique set challenges, among which is the logistical challenge providing sterile surgical instruments to surgeons. Transport and supply constraints limit quantity variety available in field sterilization equipment often not support on hand. Furthermore, it difficult predict exact type needed by surgeon field.New manufacturing technology offers compelling solution overcome challenge. Durable, biocompatible plastic resins can be formed into any shape...
Additive Manufacturing (AM) has been called the Second Industrial Revolution [1]. This technology allows a three dimensional shape defined in digital space to be directly rendered into tangible object. The transformation from virtual object by AM is fast and inexpensive compared most traditional fabrication approaches. Thus, revolutionary aspect of additive not uniform mass production first Revolution, but customization manufactured devices [2].The history surgical instruments, such as...
Three-dimensional (3D) printing technology has impacted many clinical applications across medicine. However, 3D for Minimally Invasive Direct Coronary Artery Bypass (MIDCAB) not yet been reported in the peer-reviewed literature. The current observational cohort study aimed to evaluate impact of half scaled (50% scale) printed (3DP) anatomic models pre-procedural planning MIDCAB.
A new class of Unmanned Aerial Vehicle (UAV) is investigated, based on the flying ducted fan concept. The vehicle uses a mechanically simplified control approach employing synthetic jet active flow in lieu moving surfaces or articulated rotor blades. As result, UAV's propulsion and systems are to single part, fixed pitch propeller. This mechanical simplicity makes application particularly attractive for development mini micro UAVs. separation over lifting surface as means discrete state...
This paper confirms the finding of discrete quasi-periodic streamwise vortical structures in radial flow behind separation line over a rotor blade undergoing dynamic stall forward flight. It follows our such transient induced by an inflow obstructer hover facility. Co-rotating suggest that free shear layer formed at rolls up into cells. The spanwise spacing is approximately height separated region. presence these helps explain nature variation from root to tip This, as far we know, first...
The application of leading edge separation control at full scale on a 2.8m wing-span model UAV, nicknamed STINGRAY. configuration is tailless wing-body based low aspcct ratio modified delta planform with 50' sweep. A full-scale wind tunnel test was conducted this in the NASA Langley 14x22 Tunnel. investigated high angle attack lift, drag and moments; as augmented by synthetic jet control. Flow achieved via leading-edge array piezoelectric actuators. Control authority pitch roll 11)bserved...
Direct control of circulation about the nacelle a ducted fan VTOL 1 hruster is investigated as means overcoming off design point performance deficiencies. Experimental studies were conducted on powered model outfitted with devices based Coanda effect. The intended to tailor more fworable condition for static thrust operation. Circulation jet momentum and slot parameters in order explore rpace. approach shown be effective, but also closely coupled t11e devices.
Medical device prototyping and 3D printing has been on the rise in past two decades [1]. Sterility of medical devices prolonged assured sterility a challenge because complex shapes/contours nature raw material used as build material. Certain materials may be heat-sensitive others not suited for exposure to aggressive disinfectants cleaning agents. Storage such fabricated 12-month period time ‘sterile’ conditions until use is major technological challenge. In this study, novel approach was...
The Georgia Tech Aerial Robotics Team has been working on autonomous control of an unmanned aerial vehicle for three years as both a research project and competition entry. annual International Autonomous Vehicle Competitions (1991-93) have attracted university teams from across the country well Europe, Canada, Asia. At third in June 1993, system was awarded first place demonstrating completely flight including safe landing. This success is result overcoming numerous challenges faced white...
In an earlier paper describing this research, the experimental setup and testing for a NACA 0015 three-dimensional wing employing Synthetic Jet Actuators (SJAs) in leading edge was discussed. The previous discussed effectiveness of SJAs as control effectors, useful reattaching flow at stall providing authority with zero net mass flux. This will continue discussion these actuators focusing on two actuator sets placed upper lower trailing edges airfoil various shapes to maximize effectiveness....
Active and passive approaches to control the velocity concentration of a high speed round particle-laden jet are investigated experimentally using stereo PIV system. flow field particles’ fields, via addition swirl carrier jet, has shown have significant effect in altering both phases. Control is also affected by placing pins at exit plane, which results alteration planes across normal pins. Furthermore, mixing increased spreading rate modified. Depending on number used their azimuthal...
