Flight loads monitoring of USFS aerial supervision modules
(American Institute for Aeronautics and Astronautics, Inc., 20140117)The USFS has collected flight data on Beechcraft King Airs which are being used as Aerial Supervision Modules. Data from seven aircraft is presented. The missions are separated into four flight phases: climb, cruise, ... 
Flight loads spectra of two business jets
(American Institute for Aeronautics and Astronautics, Inc., 20140117)Operational flight loads have been analyzed from two business jets, a Global 5000 and a Global Express XRS. It is shown that due to the differing nature of their missions, both airframes were subjected to nearly the same ... 
Fracture mechanics of sandwich structures
(Wichita State University, 201305)Over the past few decades both the demand for knowledge as well an increase in the application of composite materials has boomed. This has led to an intensive focus by the research community to gather information and ... 
Frequency and time domain analysis of an aeroelastic wing multiple component structure
(Taylor & Francis Group, 20150902)A multiple component structure consisting of two EulerBernoulli beams connected to a rigid mass is used to model the heave dynamics of a wing micro air vehicle. In the time domain, the attainment of a C0semigroup in the ... 
Generalization of the collision cone approach for motion safety in 3D environments
(Springer, 201202)Avoidance of collision between moving objects in a 3D environment is fundamental to the problem of planning safe trajectories in dynamic environments. This problem appears in several diverse fields including robotics, air ... 
A greedy random adaptive search procedure for multirendezvous mission planning
(Univelt, Inc., 201501)The paper proposes a new algorithm to optimize a sequence of rendezvous maneuvers by a spacecraft with multiple targets. The algorithm consists of two phases: the first phase generates feasible solutions of the problem ... 
Highorder incompressible Navierstokes equations solver for blood flow
(Wichita State University, 201207)A highorder finite difference solver was written to solve the incompressible NavierStokes (NS) equations and was applied to analyze the blood flow. First, a computer code was written to solve incompressible Navier Stokes ... 
Hybrid parallelization and optimization of a higherorder NavierStokes equation solver
(Wichita State University, 201512)With the contemporary emerging transition for the past two decades in highperformance computing (HPC) towards clusters of nodes, it is possible to obtain an efficiently scalable computational fluid dynamics (CFD) code by ... 
A hybrid scheme for the numerical simulation of shock/discontinuity problems
(Taylor & Francis, 2011)To address accuracy issues for direct numerical simulation, a hybrid scheme based on the weighted compact scheme (WCS) and weighted essentially nonoscillatory (WENO) scheme is developed. The new hybrid method incorporates ... 
Ice particle trajectory simulation
(Wichita State University, 200512)Large ice particles shed from an airframe can cause damage to downstream aerodynamic surfaces and aft mounted engines. A simulation tool was developed to compute the trajectories of shed ice particles and determine the ... 
Inplane shear response of laminated composites at high strain rates
(Wichita State University. Graduate School., 20060428) 
Kinetics of prepreg epoxy resin curing for aircraft body repair
(Wichita State University. Graduate School, 20140425)Curing is the crosslinking of polymer chains, which results in toughening of polymer material and it is widely used in bonded composite repair for aerospace components. The main objective of this project is to analyze ... 
Load rate effects on Interlaminar fracture toughness of composite materials
(Wichita State University. Graduate School, 20090501)The energy dissipation due to the failure of composites is of particular interest for crash applications involving dynamic loading. Separation of layers or delamination which can occur in opening (modeI) is one of the key ... 
Load rate effects on the crush response of laminated corrugated beams
(Wichita State University. Graduate School, 20100423)This experimental study addresses the progressive crushing responses of laminated corrugated beams fabricated using Newport NB321/7781 Eglass prepreg material. Stacking sequences of [0]n and [45]n where n=4,8 and 12 have ... 
Local bending containment in impact damaged sandwich panels
(Wichita State University. Graduate School., 20070427)A repair technique involving the containment of local bending of sandwich facesheet by strategically filling honeycomb core cells has been explored to improve the damage tolerance of impact damaged sandwich panels. The ... 
Local bending containment in sandwich panels with subsurface core damage
(Wichita State University, 200805)The compressive residual strength and behavior of impact damaged sandwich panels are governed by the amount of nonvisible core damage underneath the facesheets. The failure modes under inplane compressive loading are ... 
Low thrust orbitraising using nonsingular orbital elements and proximity quotient approach
(Univelt, Inc., 2015)Recent years have shown a growing interest in the space industry in allelectric satellites. Mission designers analyzing the optimal deployment options for all electric satellites need to consider three important metrics: ...
