Preliminary Design / Analysis (PDA)

Essig engages clients through the Design and Analysis cycle to undertake design concepts, create frameworks, and provide analysis to establish the parameters for final design.

  • CFD Analysis

Essig utilizes Computational Fluid Dynamics (CFD) to simulate fluid motion using numerical approaches for prediction purposes. By using CFD we can also analyze problems related to laminar and turbulent flows, incompressible and compressible fluids and multiphase flows.

In addition, an integral part of computational fluid dynamics (CFD) analysis is understanding how velocity, pressure, temperature and density of moving fluid impacts the product design process.

  • Heat Transfer

Essig will work to specify thermal conductivity, density and specific heat alongside the initial temperatures, solution time and time increments. By using Heat Transfer analysis we’re able to predict thermal energy exchange between two or more physical systems.

  • Stress

Stress Analysis is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. Essig performs Stress Analysis for aviation hardware while in the design phase of jet engine parts.

  • Frequency

Essig completes frequency analysis of jet engine hardware by developing an automatic method for extracting jet engine features from the joint time-frequency representation of jet engine modulation signals.

  • Lifing

Experienced members of the Essig team provide fatigue analysis of structural components. Track Life Limited engine hardware that is characterized to the degree of life consumption and replaced at a time certain date. Life consumption is established for parts that are subjected to low cycle fatigue, creep, oxidation as predominant life-limiting modes under normal engine operation.
