Performance analysis of aircraft composite winglet

B‐spline based on vector extension improved CST parameterization algorithm

“…[6][7][8][9][10] However, the development of the fighter has been transferred from the past when the high-altitude, high-speed performance was emphasized to today when the high maneuverability of the high subsonic speed and transonic speed in low-and medium-altitude, among others, is emphasized. [11][12][13][14][15] It is well known that the quality of the shape design of the aircraft is one of the important factors that can determine whether the aircraft is enabled sufficient lift to keep it flying, whether the aircraft has good maneuverability and stealth performance, and whether the aircraft can have good aerodynamic performance. [16][17][18][19] The first step of the shape design of the aircraft is to parameterize the shape, which has a critical influence on the success of the aircraft design and directly affects the overall project progress.…”

“…Civil aircraft can only survive the fierce competition in the market when it is economical, safe, and reduces its manufacturing cost to the highest possible extent 6‐10 . However, the development of the fighter has been transferred from the past when the high‐altitude, high‐speed performance was emphasized to today when the high maneuverability of the high subsonic speed and transonic speed in low‐ and medium‐altitude, among others, is emphasized 11‐15 …”

An exclusive hand protection device made of fused deposition modelling process using poly (lactic acid) polymer

“…Additionally, a greater focus on on-campus production provides for greater independence from external suppliers and fewer stockpiling requirements. Clinical processes will be more adaptable, and patients will have more control in times of crisis, but new regulations will need to be developed to keep up [41] . In the near future, it will be possible to print ready-to-use sterile parts in a cleanroom using special printing equipment.…”
