Manifold and base casting of Lunenburg Foundry Atlantic Marine Engine

Abstract

Previous work started by mechanical engineering students in the spring of 2016 established a basis for applying modern machining and modeling techniques to the fabrication of century old sand cast designs, specifically a Lunenburg Foundry Atlantic Engine. This project was continued by mechanical engineering students in the spring of 2019. From there, this groundwork was used to fabricate one of the remaining parts of the engine, the lower base. Due to COVID-19 pandemic and MIT campus shut down, this thesis project was virtualized. From this, casting simulation software (Visual Cast) used to simulate the casting of another engine part, the manifold, with a variety of geometries and process conditions. The simulations were completed to predict the casting quality of the part if physically cast. Additionally, the next steps for completion of the engine are outlined.
