Optimal aerodynamic shape design aims at finding the minimum of a functional by controlling the PDE modeling the flow using surface deformation techniques. As a solution to the enormous computational resources required for classical shape optimization of functionals of aerodynamic interest, probably the best strategy is to use in a systematic way, methods inspired in control theory. One of the ...

ownload purpose of this study was to determine the anticancer efficacy of 1,1-bis (3′-indolyl)-1-(p-biphenyl) ne (DIM-C-pPhC6H5) by inhalation delivery alone and in combination with i.v. docetaxel in a murine for lung cancer. An aqueous DIM-C-pPhC6H5 formulation was characterized for its aerodynamic propTumor-bearing athymic nude mice were exposed to nebulized DIM-C-pPhC6H5, docetaxel, or combi...

GyroWheel is an innovative device that combines the actuating capabilities of a control moment gyro with the rate sensing capabilities of a tuned rotor gyro by using a spinning flex-gimbal system. However, in the process of the ground test, the existence of aerodynamic disturbance is inevitable, which hinders the improvement of the specification performance and control accuracy. A vacuum tank t...

In the present study, we have developed a smart flapping wing with a MFC (macro-fiber composites) actuator. To mimic the flying mechanisms of nature’s flyers such as birds or insects, the aerodynamic characteristics related to the birds and ornithopters are investigated. To measure the aerodynamic forces of flapping devices, a test stand consisting of two loadcells is manufactured, and the dyna...

The achievement of flight with manned, powered, heavier-than-air aircraft in 1903 marked the beginning of a new era in the means of transportation. A special advantage for aircraft was in speed. However, when an aircraft penetrates the air at very high speeds, the disturbed air is compressed and there are changes in the density, pressure and temperature of the air. These compressibility effects...

In the present paper, the controlled flight of fruitflies after voluntary takeoff is studied. Wing and body kinematics of the insects after takeoff are measured using high-speed video techniques, and the aerodynamic force and moment are calculated by the computational fluid dynamics method based on the measured data. How the control moments are generated is analyzed by correlating the computed ...

3D techniques are increasingly used in aerospace industry to improve quality and performance of aircrafts. This paper presents a 3D imaging technique for studying the aerodynamic shape and flight performance of micro air vehicles. 3D stereoscopic vision, based upon stroboscopic imaging, was utilized to obtain the 3D information of the aircraft’s flexible aerodynamic surface. The aircraft models...

The dynamics of a quadrotor are a simplified form of helicopter dynamics that exhibit the same basic problems of underactuation, strong coupling, multi-input/multi-output design, and unknown nonlinearities. Control design for the quadrotor is more tractable yet reveals corresponding approaches for helicopter and UAV control design. In this paper, a backstepping approach is used for quadrotor co...
