Final answer:
The small wing-like protrusions on each side of the nose on the MD80 aircraft are called nostril strakes, and they contribute to the aerodynamic stability of the aircraft during phases of high angle of attack like take-off and landing.
Step-by-step explanation:
The small wing-like protrusions on each side of the nose of an MD80 aircraft are known as nostril strakes or sometimes as – nose strakes. These strakes play a crucial role in enhancing the aerodynamic stability of the aircraft, particularly during take-off and landing. The design and function of these strakes are a result of advanced aeronautical engineering, which involves the study of forces and the physical properties of aircraft to improve performance and safety.
The nostril strakes help to direct airflow around the fuselage and prevent airflow separation, which can lead to a stall. In simpler terms, they work to keep the aircraft stable by managing wind flow when the angle of attack is high. It's also worth mentioning that the presence of nostril strakes on the MD80 is part of what makes this aircraft model unique, as not all airplanes feature this specific design element. Understanding the design and function of various aircraft components, including nostril strakes, is essential for those interested in aeronautics and aviation engineering.
