Because the CFD was broken into 321 individual surfaces, careful attention was taken to choose a sufficient set of surfaces to represent either the wing or ...
The maneuvering load is significantly correlated with the pilot's operation, thus indicating the maneuvering motion of the aero-engine during the actual flight. Accordingly, the establishment of accurate distribution models is of great engineering
The V-speed designator for Vs is the stall speed. Point A is the positive load factor limit, and the V-speed designator for Va is the maneuvering speed. Maneuvering speed is the airspeed corresponding to point A. It is important not to exceed the load factor limit at speeds slower than point A because the airplane will stall first.

In addition, under any rub-impact stiffness, the larger the maneuvering load, the stronger the rub-impact response of the system. Therefore, the rub-impact stiffness should take an appropriate value within a small value range. (2) The larger the speed and maneuvering load requirements, the larger the value of the oil film clearance should be.
TURNS. Increased load factors are a characteristic of all banked turns. As noted in the section Load Factors in Steep Turns and particularly Figs. 17-48 and 17-49, load factors become significant both to flight performance and to the load on wing structure as the bank increases beyond approximately 45 degrees. The yield factor of the average ...
The design maneuvering speed (V A) is the speed at which the airplane will stall before exceeding its design limit-load factor in turbulent conditions or when the flight controls are suddenly and fully deflected in flight. Under these conditions the airframe experiences an increase in "G-force" or "load factor."

Maneuvers in level ice are common operations for icebreakers and polar supply vessels. Maneuvering exposes the midship and stern area to ice interaction, influencing the magnitude and frequency of ice-induced loading in these areas. However, full-scale measurements do not typically cover the midship and stern areas, as …
