Rapid response of rice plants to arsenite toxicity

Absorption of arsenic (As) by plant root is an essential activity that bridges the soil As concentration and physiological responses which can be monitored soon after exposure to As. In the present study, physiological responses to short exposure to arsenite (AsIII) was compared in two indigenous rice cultivars one adapted to temperate and humid (TH) and the second one to warm and humid (WH) cl...

Rotor Wake/Fixed Wing Interactions with Flap Deflection

The basic features in the interaction of a rotor wake with a wing in low-speed forward flight are studied using low-speed wind tunnel experiments. The configuration captures several of the aerodynamic interactions in the tiltrotor transition phase, and during wake/empennage interactions. Previous work showed that the pressure field on the wing surface below the rotor is dominated by n-per-rev "...

Adaptive Control of Separated Flow

Adaptive closed-loop control is used to optimize the lift-to-drag ratio of post-stall separated flow over a NACA 0025 airfoil using multiple amplitudemodulated (AM) or burst-modulated (BM), zero-net-mass-flux (ZNMF) actuators that cover the central 33% span of the airfoil. A simplex optimization approach uses the lift and drag measured by a strain-gauge balance for feedback and searches for the...

Fan Flow Deflection for Supersonic Turbofan Engines

We present an initial parametric investigation of fan flow deflectors for suppressing noise from supersonic turbofan engines. Realistic exhaust geometry and flow conditions for bypass ratio 2.7 were simulated in a subscale experiment. The study encompassed acoustic measurement and mean velocity surveys. The deflectors comprised internal vanes with both symmetric and cambered airfoil sections an...

Fan Flow Deflection in Simulated Turbofan Exhaust

Fan flow deflection for jet noise reduction was applied to subscale nozzles simulating the geometry and exhaust conditions of separate-flow turbofan engines. Two types of deflectors were tested, one comprising two pairs of vanes internal to the fan duct and the other consisting of a wedge positioned outside the fan duct. The noise reduction achieved by the vanes was strong in the downward direc...
