TUBITAK-UZAY (previously TUBITAK-BILTEN) has launched a new satellite mission project known as RASAT after BILSAT-1's successful launch. In RASAT, the aim is to develop new subsystems those will replace the legacy systems incrementally which are off-performance or obsolete. OBDH subsystem on BILSAT-1 platform contains systems with obsolete parts, like on-board computers. Also, in future's earth imaging satellite missions, large amount of data will likely be generated on-board, increasing the performance requirements of the OBDH subsystem. A new generation on board computer, code named BILGE, together with its flight software and ground station software has been developed.

Feasibility study on thermal survivability of X-Band subsystem on RASAT microsatellite Okan, A (2005-06-11) After the launch and commissioning of the first Turkish remote sensing satellite BILSAT-1(center dot), TUBITAK BILTEN has initiated the RASAT microsatellite project. RASAT will be a remote sensing microsatellite at low Earth orbit (LEO), with a mass of around 100 kg and an orbital average power of 38W. RASAT is planned to he launched in 2007 and will be the first satellite to be designed and manufactured entirely in Turkey.
Tilt duct vertical takeoff and landing uninhabited aerial vehicle concept design study Armutcuoglu, O; Kavsaoglu, MS; Tekinalp, Ozan (American Institute of Aeronautics and Astronautics (AIAA), 2004-03-01) A new autonomously controlled tilt-duct vertical takeoff and landing uninhabited aerial vehicle concept is proposed. This design combines the vertical flight capability of a helicopter and forward flight performance of a fixed-wing conventional aircraft. The two main engines and propellers are located inside the tilting ducts attached to the wing tips. There is a third engine-propeller combination located inside the all fuselage for pitch and yaw control during hover and transition. The advantages and disad...
High-lift design optimization using Navier-Stokes equations Eyi, Sinan; Rogers, SE; Kwak, D (American Institute of Aeronautics and Astronautics (AIAA), 1996-05-01) This article presents a design optimization method for maximizing lift without increasing the drag of multielement airfoils at takeoff and landing configurations. It uses an incompressible Navier-Stokes dow solver (INS2D), a chimera overlaid grid system (PEGSUS), and a constrained numerical optimizer (DOT). Aerodynamic sensitivity derivatives are obtained using finite differencing. The method is first validated with single-clement airfoil designs and then applied to three-element airfoil designs. Reliable d...
Investigation of rotor wake interactions in helicopters using 3d unsteady free vortex wake methodology Yemenici, Öznur; Uzol, Oğuz; Department of Aerospace Engineering (2010) This thesis focuses on developing and examining the capabilities of a new in-house aerodynamic analysis tool, AeroSIM+, and investigating rotor-rotor aerodynamic interactions for two helicopters, one behind the other in forward flight. AeroSIM+ is a 3-D unsteady vortex panel method potential flow solver based on a free vortex wake methodology. Validation of the results with the experimental data is performed using the Caradonna-Tung hovering rotor test case. AeroSIM+ code is improved for forward flight cond...
Development of control allocation methods for satellite attitude control Elmas, Tuba Çiğdem; Tekinalp, Ozan; Department of Aerospace Engineering (2010) This thesis addresses the attitude control of satellites with similar and dissimilar actuators and control allocation methods on maneuvering. In addition, the control moment gyro (CMG) steering with gyroscopes having limited gimbal angle travel is also addressed. Full Momentum envelopes for a cluster of four CMG's are obtained in a pyramid type mounting arrangement. The envelopes when gimbal travel is limited to plus-minus 90 degree are also obtained. The steering simulations using Moore Penrose (MP) pseudo...
