Numeriqs Introduces the Legal Description Reader for AutoCAD Surveyors Need
Numeriqs introduces Legal Description Reader for AutoCAD, a metes and bounds parsing tool built to convert legal text into structured boundary geometry inside AutoCAD. The software reads bearings, distances, curves, and alias references, transforming written descriptions into drawable line and arc segments with full visibility into closure and computation. Legal…
Introducing Numeriqs software and the Launch of Proc for AutoCAD
We’re proud to announce the launch of Numeriqs, our new software brand, focused on precision computational tools for CAD and engineering professionals. Numeriqs began with a simple idea — to make advanced analytical methods accessible in practical, field-ready software. It serves technical professionals who value reliability, clarity, and control. Our…
Diffuser Frustration
I have spent an inordinately long period of time resolving the intricacies in combustor diffuser. Considering the lower temperatures we are dealing with, pressure losses can be rather devastating. As a result, I looked at a myriad of texts and methods to develop our pressure model for our combustion system.…
Swirl Distribution in Low Hub/Tip Ratio Blades
The low pressure (LP) fan and high pressure (HP) compressor are designed in a similar manner. These both suffer from design problems that are exacerbated by low hub/tip (h/t) ratio blades. One such problem is blade twist. We wanted to compare four vortex theory models, including Mixed-Vortex swirl distribution and three…
HP Compressor and Turbine Update
The axial flow turbofan HP compressor and turbine were, and continue to be, a battle between size, efficiency, and power. These two components affect the overall performance of the engine. While the design is still an on-going challenge, I can see the fun parts coming. Materials and elegantly designed component…
Turbofan Research – Combustor Design Challenges
I have been involved in a small footprint turbofan for a few years now. While the overall parameters of each engine section are understood, the intricacies of achieving each requirement are mind-boggling. Currently Aerospace Research and Development Group, LLC (AeroRND) is neck deep in the annular combustor design challenges (burner…
Small Footprint Turbofan Research
I have studied turbofan theory and design for over 3 years straight. My pet project, a small footprint turbofan, came with me to Aerospace Research and Development Group, LLC. (AeroRND). The project has taken on new dimensions and has grown a life of its own (like Frankenstein, only the Mel…
