Arospace Engineering Assignment Report On Aircraft Design 2025

Assignment:

You are expected to submit a PDF summary report detailing the aircraft design process you’ve developed. The report should be structured with clear sections, contain updated improvements (highlighted in a different font colour),  and include appendices for supporting material. Plus a CAD Design.

Full Report Structure & Instructions

Introduction (½ Page) – [8 Marks]

Include:

• Mission requirement (e.g. range, capacity, speed)
• Design process (logical sequence of design steps)
• Predicted performance:
  • Payload (kg)
  • Range (nm)
  • MTOW (kg)
  • Cruise Mach number
  • Take-off field length (m)
  • Wing area (m²)
  • Wing span (m)
  • Total thrust (kN)

• Tip: Pull this from Assignment 3 and highlight any updates in a different colour font.

Market Analysis (½ Page) – [10 Marks]

Include:

• Short analysis of your aircraft’s market
• Supporting data table(s) ➝ place in Appendix A

• Tip: Market research should align with your mission requirement.

Sizing Process (1 Page) – [12 Marks]

Include:

• Brief explanation of how you chose your design point (W/S and T/W)
• Sizing diagram
• Comparison plot (your design vs. competitors)
• Supporting equations ➝ place in Appendix B

MTOW Process + Payload (½ Page) – [10 Marks]

Include:

• Explanation of how MTOW was estimated
• OWE vs MTOW plot
• Payload breakdown ➝ as a table in the main body
• Supporting equations ➝ Appendix B

Cabin Design (1–1½ Pages) – [10 Marks]

Include:

• Your cabin design concept
• Decisions made during the phase (layout, capacity, comfort, etc.)
• Images cropped from Assignment 4 drawing ➝ place in Appendix C

Wing Planform (1 Page) – [10 Marks]

Include:

• Factors considered in your planform design (no equations)
• Resulting planform diagram

• Reference: [EG2100 Wing Planform Tutorial.pdf]
• Covers: sweep angle, taper ratio, crank design, MAC location, etc.

Tail Sizing + Scissors Diagram (1–1½ Pages) – [10 Marks]

Include:

• Scissors diagram
• Description of HTP sizing & tail volume coefficient
• Fin volume coefficient (with justification)

• Reference: [EG2100 Tail Sizing Tutorial.pdf]

Engine Selection (½ Page) – [8 Marks]

Include:

• Justify engine choice
• Scaling calculations (if adapting existing engines)
• Must align with thrust requirement

GA Drawing – [12 Marks]

Include:

• General Arrangement drawing in Appendix D

Concluding Remarks (1 Page) – [10 Marks]

Include:

• Reflection on the design process
• What informed your decisions
• How knowledge of:
  • aerodynamics
  • propulsion
  • structures
  • flight dynamics
  • control systems
    …would help in later stages.

References Section

• Add any textbooks, academic sources, aircraft data, or tools used.
• Place this before the Appendices.Appendices Checklist

• Appendix A – Market analysis tables
• Appendix B – Supporting equations (sizing, MTOW, etc.)
• Appendix C – Cropped cabin drawings
• Appendix D – GA drawings
