A History of Engineering in 100 Objects: Model of the Napier Sabre V

IMechE | February 12, 2019

The Napier company began developing large aero-engines towards the end of World War One. The Lion, in modified form, had powered several of the Supermarine competitors in the Schneider Trophy air races and several land speed record cars. However, by the late 1920s, work had started on replacements. Two H-block designs, the H-16 Rapier and the H-24 Dagger, were produced. The H-block consisted of two horizontally opposed engines, lying one atop or beside another.
In 1927, Harry Ricardo published a study on the concept of the sleeve-valve engine. He argued that traditional poppet-valve engines would be unlikely to produce much more than 1,500hp; to pass this limit, a sleeve valve would have to be used, to increase volumetric efficiency. Ricardo started work with Bristol Engines on sleeve-valve designs and Major Frank Halford began work with Napier.

Procore Works with AWS to Bring Digital Twins to the Construction Industry

Procore | July 16, 2022

Procore Technologies, Inc.a leading global provider of construction management software, today announced it is working with Amazon Web Services (AWS) to leverage AWS IoT TwinMaker to extend the value of construction data into facility operations. The tools AWS IoT TwinMaker provides accelerate the creation of digital twins for buildings, factories, industrial equipment, and production lines. Procore’s platform serves to connect all construction stakeholders in the lifecycle of a built asset. AWS IoT TwinMaker will allow Procore data to be integrated from design and construction into operations. Procore project owners will be able to incorporate as-built information from Procore with real-time data sources using TwinMaker, extending the value of construction information into operations. This consolidation of information can streamline operations and maintenance and enable lifecycle analysis of portfolio assets. “We’re very excited about our partnership with AWS. Roughly 80% of the lifecycle cost of a project is in the operations phase, With this partnership we can leverage Procore’s course of construction data during that operations phase to help owners reduce costs, optimize performance, and be better prepared for future project needs.” -Tiffany LaBruno, product director, owners at Procore. AWS IoT TwinMaker will make it faster and easier to create digital twins of real-world systems. Using AWS IoT TwinMaker, developers can get started quickly building digital twins of devices, equipment, and processes by connecting AWS IoT TwinMaker to data sources like equipment sensors, video feeds, and business applications. Built-in connectors for integration with sensors, 3D visualization, and downstream data analytics are transforming the built environment.
