CORE was written to facilitate optimization and design space exploration in the conceptual design phase or rotorcraft
CORE was written to facilitate optimization and design space exploration in the conceptual design phase or rotorcraft. The nature of the design problem for helicopters, and especially compound helicopters, which CORE also supports to an extent, requires tools for optimization and visualization of a multi-dimensional problem with many objectives and constraints. CORE employs built-in optimization for both global and local search using established algorithms, both non-deterministic and deterministic. To let the designer visually explore the design space, novel capabilities are also included that combine well-known techniques for visualizing multi- and hyper-dimensional design domains into a single matrix of linked plots that allows the visualization of the effect of multiple decision variables on many constraints and design objectives.
The architecture of the suite was designed such that it can be used in a generic, rather than ad hoc, manner, while still offering significant transparency and expandability to the user. The goal of the project was to create a software suite that not only facilitates iteration and optimization, but in the process of converging on a design point also gives the designer a truly good understanding of the design problem, the design space, and what requirements are driving the design.
The analysis methods are able to capture important phenomena at the flight envelope boundaries, such as retreating blade stall, reverse flow, and advancing blade critical Mach drag rise.
CORE was designed to be operable by an engineer familiar with Matlab10 (the chosen language for the project) but little or no knowledge of rotary wing aerodynamics and optimization algorithms. This means that when presented to final year undergraduate students, they should find it useful, clear, and not daunting as a tool to aid in sizing a conventional helicopter for an undergraduate-level design task. However, when presented to an engineer with industrial experience, he/she should find the suite architecture to have sufficient modularity, transparency, and expandability to easily cater it to a more specific task and tune it to compliance with the appropriate level of technical ability within the company.
Further development will need feedback from many users, especially rotorcraft experts.
