A new capability for the prediction of aerodynamic characterisitic of powered-lift vehicles is the goal of thisproject. a presently available aerodynamic analysis computercode, vsaero, is applicable to powered-lift aircraft configurations. the program includes a method which can treat the difficult… More

Subsonic and transonic aerodynamic analysis procedures have been developed for application to circulation control airfoils. while these methods perform well in comparison with experiments for low blowing coefficients, at high blowing coefficients, with the nozzles choked and producing underexpanded… More

The objective is to develop a tool for designing vortex flaps on advanced fighter aircraft including the effects of viscosity. analytical methods, inc. proposes to use an unsteady time-stepping version of its surface singularity panel method, vsaero, as a basis for this work. this will generate the… More

The flow field about powered lift vehicles can become very complex due to high angles of attack and lifting jets. in addition to modeling propulsion/airframe interactions, therefore, flow prediction methods must treat the problems of separation and the transient effects of passing vortical… More

A program of study is proposed which will lead to a practical analysis capable of calculating the flow around and the loads on configurations where elements of the vehicle are in motion relative to each other and where the vehicle itself may be in unsteady motion in the inertial frame. a wide range… More

Because of the complexity of the helicopter flow field, a zonal method of analysis of computational aerodynamics is required. in this research, a new procedure for coupling potential and viscous flow calculation schemes is proposed. an over-lapping, velocity-coupling technique is to be developed… More

The Navy's plan to launch and retrieve Unmanned Undersea Vehicles (UUVs) from submarines will require precise control of the UUV when it is in close proximity to the submarine hull. The hydrodynamic forces experienced by the UUV when it is near the submarine are significantly different from those it… More

A Cartesian, multigrid, Euler solver is investigated for development as a module suitable for the multidisciplinary design optimization (MDO) environment. The ultimate objective is not to improve the Euler solver (it is already a mature code) but rather to augment or replace the linear panel method… More

Robotic researchers currently are using insufficient and varying robot platforms to investigate issues crucial to the successful development of a remote reconnaissance tool for the urban search and rescue (USAR) community. USAR robotic researchers need a standard robot platform designed for research… More

DESCRIPTION (provided by applicant): Despite significant recent government and private-sector efforts to improve the current state of the art in bone marrow transplants, many patients still suffer from lack of adequate matching bone marrow inventories and from severe treatment-related… More

DESCRIPTION (provided by applicant): Three primary sources of hematopoietic stem cells (HSCs) are routinely used in HSC therapy. These include mobilized peripheral blood, bone marrow and umbilical cord. While each source has its individual benefits, cord blood has seen increased usage over the past… More

DESCRIPTION (provided by applicant): The three primary sources of hematopoietic stem cells (HSCs) for bone marrow transplant are: mobilized peripheral blood, bone marrow, and umbilical cord. While each source has its individual benefits and limitations, cord blood has seen increased usage over the… More

DESCRIPTION (provided by applicant): In the present STTR we propose to investigate two novel approaches in our exploration of the therapeutic and regenerative potential of cell-based medicine. Furthermore, we will utilize a preclinical animal model of compression syndrome (CS) that mimics the… More
