Two-Dimensional Shock Sensitivity Analysis for Transonic Airfoils with Leading-edge and Trailing-edge Device Deflections
… drop, was to determine if the incorporated 2-D airfoil exhibits abnormal shock sensitivity. A comparative airfoil study was used to determine if this particular transonic airfoil is prone to abrupt shock movement, resulting in increased regions of separation.

Gradient-Based Optimum Aerodynamic Design Using Adjoint Methods
… coefficient, at fixed lift coefficient, for 2-D transonic airfoil flows. Reduced gradients of several functionals are derived through application of a Lagrange Multiplier Theorem. The adjoint system is carefully studied including the adjoint characteristic boundary conditions at the far-field …

Two-dimensional Euler computations on a triangular mesh using an upwind, finite-volume scheme
… wedge inlet, and several AGARD 07 working group transonic airfoils. In general, the solutions computed by the upwind solver on the unstructured grids were as accurate as upwind solutions on a structured mesh. The blunt body solution, and some of the transonic airfoil solutions on the unstructured …

Aerodynamic characterization of a Griffith-type transonic, laminar-flow airfoil
… was conducted at the University of Illinois’ Transonic Wind Tunnel Facility on a Griffith-type transonic airfoil to evaluate the effectiveness of its laminar flow qualities and boundary-layer flow-control characteristics in the transonic regime. Airfoil surface and wake pressure data were …

Optimization Techniques Exploiting Problem Structure: Applications to Aerodynamic Design
… nozzle design problem involving one-dimensional transonic flow. An initial formulation as an optimal control problem allows us to solve the problem as as two-point boundary problem which provides useful insight into the nature of the problem. Using the Reduced Hessian formulation for this …
