Analysis Of Coupled-Resonator Slow-Wave Structures For Traveling-Wave Tubes For Aerospace Applications
(2009-04-30)
Through continued innovation and growth, traveling wave tube amplifiers (TWTAs) remains the microwave power amplifiers of choice in a wide range of high power microwave and millimeter-wave applications specifically for ...
Piezoceramic Dynamic Hysteresis Effects On Helicopter Vibration Control Using Multiple Trailing-Edge Flaps
(2009-07-14)
Helicopters suffer from severe vibration levels compared to fixed-wing aircraft. The main source of vibration in a helicopter is the main rotor which operates in a highly unsteady aerodynamic environment. Active vibration ...
Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)
Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ...
Aerodynamic Analysis Of Grid Fins Using Analytical And Computational Methods
(2009-07-16)
Grid fins (lattice fins) are used as a lifting and control surface for highly manoeuvrable missiles. Grid fins also find their applications for air-launched submunitions. The main advantages are its low hinge moment ...
