Experience
Mr. Hladio joined MR&D in November of 2003. At MR&D, Daniel is active in several programs related to modeling, design, and analysis of high temperature composites, heat shields, leading edges, and refractory metals for various aerospace applications. Mr. Hladio has extensive experience in the analysis and design of high temperature composite materials and refractory metals.
Recently Mr. Hladio has been involved in the design of chemical vapor deposition (CVD) rocket nozzles. The design is based on a transient thermal structural model that computes temperatures, stresses, and strains in the throat under operating loads. The design includes the effects of residual fabrication stresses on the nozzle performance.
Mr. Hladio has worked with Williams International under contract to the Air Force to develop an expendable high speed turbine engine planned for supersonic missiles that fly at speeds approaching Mach 4. Some of the nozzle components are exposed to gas temperatures that exceed 3000°F making CMC’s an attractive alternative material. Recommendations on material candidates, component design, and component testing were made after extensive analysis.
The hot isostatic pressing (HIPing) methodology was developed by Mr. Hladio at MR&D. Quantitative predictions of shape distortions and density distributions were achieved by implementing constitutive models into a general finite element code simulating creep, porosity, and plasticity.
Prior to working at MR&D, Mr. Hladio was member of the Integration Testing Department and member of the Mechanics Team at ANSYS, Inc. While there he worked closely with developers to advance the capabilities of ANSYS and ensure the quality of the finite element program.
