Free viewpoint TV (FTV) enables us to view a distant 3D world by freely changing our viewpoints as if we were there. FTV will bring an epochal change in the history of television since this function has not yet been achieved by conventional TV technology. We proposed the concept of FTV and verified its feasibility using the world’s first real-time system including the complete chain of operatio...
The present study aims to numerically simulate the thrust vectoring by secondary injection. analysis of flow for this was done using ANSYS Fluent. kω-sst turbulence model used. baseline solver selected as a double-precision Density-based coupled solve with implicit time integration. Least squares cell-based spatial discretization in which solution assumed vary linearly used and second-order upw...
A full envelope database of a thrust-vectoring axisymmetric nozzle performance for the Pratt & Whitney Pitch/Yaw Balance Beam Nozzle (P/YBBN) is being developed using the F-15 Advanced Control Technology for Integrated Vehicles (ACTIVE) aircraft. At this time, flight research has been completed for steady-state pitch vector angles up to 20° at an altitude of 30,000 ft from low power settings to...
Secretion of granular glands from the skin of amphibians is a fascinating resource of active substances, particularly for cancer therapy in clinical practice of Traditional Chinese Medicine. A variety of anti-tumor peptides have been isolated from different toads and frogs; however, no anti-tumor peptides are reported in toad venom of Bufo gargarizans. Firstly, soluble fraction from fresh toad ...
There have been many advancements in the field of aerospace and avionics. Scientists have increasingly started to focus on VTOL (vertical take off and landing) aircrafts. We have built a miniature VTOL twinrotor UAV. UAVs have begun to grab a lot of attention these days due to its numerous applications such as surveillance and relief. Twinrotor is a kind of a helicopter having two main propelle...
This paper describes an approach based on using both bias momentum and multiple control moment gyros for controlling the attitude of statically unstable thrustlevitated vehicles in hover or slow translation. The stabilization approach described in this paper uses these internal angular momentum transfer devices for stability, augmented by thrust vectoring for trim and other “outer loop” control...
