T-45 Aerodynamics Student Workbook
AERO CHAPTER 02, HIGH-SPEED FLIGHT
MOTIVATION
Flight at high Mach numbers affects an aircraft differently than flight at slower speeds. Understanding the
effect of compressibility at high Mach numbers is important to you because of the effect on stability, lift,
and drag. Knowing the flight characteristics of the T-45 during high-speed flight will help you, as a pilot, to
realize the maximum potential of the aircraft.
OVERVIEW
Aircraft that are capable of high-speed flight look different from those developed for low-speed flight.
Many significant differences exist between high-speed and low-speed aerodynamics. The nature and
cause of these differences and their application to the T-45 will be discussed in this lecture.
In this lesson, we will be discussing:
The effects of high-speed flight on aircraft
Methods used to overcome the effects and permit high-speed flight
High-speed flight characteristics of the T-45
THE SUPERSONIC F-18 OPERATES IN THE HIGH-SPEED FLIGHT REGIME
AND IS CAPABLE OF MACH 1.8
