The study by Nizam BIN Dahalan and Iskandar Shah Ishak (2017) aimed to investigate the aerodynamic characteristics of a curved fin rocket. The study used a semi-empirical method and numerical solutions at various Mach numbers for subsonic and supersonic speeds and angle of …

Dec 24, 2003 · To make consistent fin airfoils by sanding balsa sheet it is easiest to work with a trapezoidal fin pattern (as compared to using a half-elliptical shape or some other curved shape). Then you can place metal wires of various diameters along the leading edge or trailing edge and use tools like a sanding block to get fairly consistent shapes.

Feb 1, 2023 · I've seen swept-back fins with curved edges in cartoons and video games , but it seems like almost every real-life rocket I've seen has rectangular fins. What exactly is the difference between these two types of fins and what are the pros and cons of each design?

Mar 31, 2025 · Swept Fins: These fins are angled backward, providing improved stability and control during high-speed flight. They're often used on smaller model rockets and are popular among beginners. Rounded Fins: These fins are curved and smooth, providing a high degree of stability and control during flight. They're often used on larger model rockets and ...

Mar 24, 2025 · Tapered swept fins model rockets are a type of model rocket that features a unique fin design, where the fins are tapered and swept backward. This design allows for improved stability and control during flight, making them …

Clipped delta fin and trapezoidal fin have 4 different sizing parameters that are root chord, span, tip chord, and thickness. Swept fin has 5 different sizing parameters that are sweep...

Mar 31, 2025 · Trapezoidal fins are the most common type, characterized by their trapezoid shape and angled edges. They provide excellent stability and are well-suited for most model rockets. Elliptical fins are curved, providing a more aerodynamic shape that reduces drag and increases speed.

This investigation seeks to discern the aerodynamic differentials between rockets featuring straight fins and those with curved fins, focusing on the drag coefficient (cd), lift coefficient (cl), and moment coefficient (cm).

Jun 1, 2023 · The aeroelastic stabilities of curved fins (or wraparound fins) in rolling motion are investigated in the supersonic flow region. Because of their inherent roll, wraparound fins are subjected...
