Aerospace Engineering

Aerospace Engineering Projects – including aircraft flight controls, landing gears, NASA heat exchangers and the Space Shuttle Main Engines.

Finite element analysis is often used to determine structural integrity of components operating in extreme environments (thermal / transient), stress, vibration & fatigue).

Recertification of Aging Pressure Vessels/ Systems at NASA Facility

We developed a seven-year program for the recertification of aging pressure vessels and pressure systems for the NASA-Glenn Research Center. Some of the vessels and systems were over forty years old, and were part of the original NACA installation. Some were layered vessels for 3-6000 psi service, some were monobloc high pressure vessels, and others …

Vibration Analysis on Linear Displacement Transducers (Actuators)

FEA Model Results O’Donnell Consulting performed a vibration (modal and spectrum) FEA analysis for a manufacturer’s linear variable displacement transducers. When a client wished to add a Linear Variable Displacement Transducer (LVDT) Unit to a stock hydraulic Actuator for a Demonstration Engine, they had concerns regarding changes in the dynamic behavior of the Actuator. We …
