Winglets are small upward-bending extensions located at the ends of commercial aircraft wings. These enhancements, which initially seemed insignificant, transformed modern aviation by boosting aerodynamic efficiency and decreasing fuel usage. These designs decrease induced drag, which are vortices created at the wingtip during flight, by
It’s difficult to define what a propeller blade is. If it’s just the shape of it, then it could be said that a screw is a propeller, though screws are rarely used as a device of propulsion. If it’s just something that converts rotational motion
Written by: Jonathan Handjojo Imagine a world where materials don’t just hold their shape after being printed—they evolve, transforming in response to their environment. This is the world of 4D printing, a groundbreaking innovation that builds on the capabilities of traditional 3D printing by introducing
A reusable launch vehicle is defined by a ScienceDirect paper as a rocket that can be recovered and launched multiple times (Kasselouri, Patroklos, & Tsikopoulos, 2023). Smaller parts like engines and boosters can also be reused, reducing launch costs significantly. In recent years, companies like
Stable Matching and its Discrepancies Written by: Aryan Mansingh There are many topics in game theory, but one of the most basic yet fundamental is the idea of a stable matching. This can be used in a variety of fields from economics to 5G networks,
