Conceptual design and analysis with Mariyam Abid

The engineering question

How do requirements and engineering assumptions become a documented conceptual aircraft?

Mariyam Abid and I developed the FireBolt aircraft concept, documenting requirements, sizing calculations and configuration decisions. We used MATLAB, RDS and CAD to connect the analytical work with the geometric design and produce a coordinated design report.

Inside the method

Method and workflow

  1. 01

    State the brief

    Define mission requirements and the assumptions driving the initial aircraft sizing.

  2. 02

    Develop the configuration

    Document the chosen architecture, airfoil and geometric decisions with their assumptions.

  3. 03

    Connect the tools

    Carry the study through MATLAB calculations, RDS records, CAD and a DATCOM adaptation.

  4. 04

    Document the design

    Record the assumptions, configuration choices and analytical results in the joint design report.

Technical notes

Model assumptions and scope

  • The results cover conceptual sizing, analysis and CAD. Detailed design and experimental validation are outside the project scope.
  • The CAD configuration and the DATCOM reference curves are separate models; the reference curves are identified in the aerodynamic-modelling case.
Potential extensions

Bring the sizing assumptions, geometry definitions and analysis inputs into a single consistent design record.
