Don't Read Chinese? No Problem

 Hey, Claude, Translate This

I've been fascinated by flapping wing aircraft ever since Dune introduced us to 'Thopters" (ornithopters) that fly like dragonflies. Ever watched a dragonfly fly? 

Want to see me fly backwards?

So there is a link* in an "Atlas" newsletter about wing flapper research, but the important part is in Chinese. I gave the problem to Claude Opus 4.6.  Of all the translation programs I've used, it's the fastest, and generates pristine english. 

PROMPT: Please interpret this into english: 摘要 本文提出了一种新颖的建模方法, 用于研究由薄且可随意变形的膜组成的双翼扑翼的推力生成机制. 基于应变能等效原理, 膜 结构通过弹簧质点系统进行建模. 气动载荷采用简化的准定常气动模型计算, 并考虑“合拢-打开”机制. 当两个翼面接触时, 系统中引入 了冲击力. 对机翼动力学数值模拟问题, 首先进行了网格收敛性分析以确定合适的网格尺寸. 为了验证所提出建模方法的正确性, 将预 测的双翼扑翼飞行器的推力和所需功率与实验数据进行了比较. 本文还分析了前进速度对推力的影响. 结果表明, 随着前进速度的增 加, 推力产生效率降低, 同时机翼变形减小.

Abstract

This paper presents a novel modeling approach for studying the thrust generation mechanism of biplane flapping wings composed of thin, freely deformable membranes. Based on the principle of strain energy equivalence, the membrane structure is modeled using a spring-mass system. Aerodynamic loads are calculated using a simplified quasi-steady aerodynamic model that accounts for a "clap-and-fling" mechanism. When the two wing surfaces make contact, an impact force is introduced into the system. For the numerical simulation of wing dynamics, a mesh convergence analysis is first performed to determine an appropriate mesh size. To validate the proposed modeling approach, the predicted thrust and required power of the biplane flapping-wing aircraft are compared with experimental data. The paper also analyzes the effect of forward velocity on thrust. Results show that as forward velocity increases, thrust generation efficiency decreases while wing deformation is reduced.

That Claude is just a mind blower, not unlike the dragonflies themselves.
