Module Aim and Summary
It is intended to prepare students to understand the customer and mission requirements of an aircraft and derive a conceptual layout including wing plan form and size, choice of propulsion system along with subsystems as well as selection criteria for navigation systems. Students are taught various aircraft characteristics and their impact on performance, stability and control. They are taught to estimate thrust requirement, select the type propulsion device and arrive at its installation along with subsystems. Students will be trained on the impact design choices have on the overall performance vis--vis mission requirement, and trained to critically evaluate each choice

Module Learning OutcomesAfter undergoing this module students will be able to:
Identify and describe requirements for different classes of aircraft
Contrast and explain the design requirements obtained based on fundamental principles and historical data
Evaluate the design specifications and then critically arrive at an aircraft design that is likely to meet the requirements
Analyse the various constraints coming from specifications and choose key parameters (total weight, wing plan form, thrust/power required etc.)
Calculate and compare performance and stability characteristics against design goals and make necessary changes to choices already made and generate a layout
Analyse design issues for aerodynamics, propulsion, structure, weights, stability, cost, and performance, and then calculate range or sizing the design to a specified mission
