17Aircraft Load
17.1 Overview
Aircraft performance depends on its structural integrity to withstand the design load level. Aircraft structures must withstand the imposed load during operations; the extent depends on what is expected from the intended mission role. The higher the load, the heavier the structure for its integrity; hence the maximum takeoff weight (MTOW) affecting aircraft performance. Aircraft designers must comply with the mandatory certification regulations to meet the minimum safety standards.
The information provided herein is essential for understanding performance considerations that affect aircraft mass (i.e. weight), hence its performance. The V‐n diagram depicts the loading condition and the limits of aircraft flight envelope. Only the loads and associated V‐n diagram in symmetrical flight are discussed herein. Estimation of load is a specialised subject covered in focused courses and textbooks [1, 2]. However, this chapter does outline the key elements of aircraft loads.
This chapter includes the following sections:
- Section 17.2: Introduction to Aircraft Load, Buffet and Flutter
- Section 17.3: Flight Manoeuvres
- Section 17.4: Aircraft Load
- Section 17.5: Theory and Definitions (Limit and Ultimate Load)
- Section 17.6: Limits (Load Limit and Speed Limit)
- Section 17.7: V‐n Diagram (the Safe Flight Envelope)
- Section 17.8: Gust Envelope
Classwork content. The chapter can be skipped if the subject has been learned about in other coursework, otherwise the readers ...
