R-4360 星型发动机

Create an interactive 3D engineering exhibit of the Pratt & Whitney R-4360 Wasp Major radial engine. Show its distinctive 28-cylinder construction, arranged in four staggered rows of seven cylinders, on a light gray technical-plate background. Use a dense three-quarter hero view, precise red and blue diagram accents, soft studio reflections, and subtle contact shadows. The experience should feel like a working museum engineering drawing.

Model the crankshaft, master and articulating connecting rods, pistons, finned cylinder barrels, cylinder heads, rocker mechanisms, valves, springs, pushrods, spark plugs, intake and exhaust manifolds, four cam rings, planetary reduction gearbox, four-blade propeller, supercharger, and supporting stand. Use cast and machined gray metal, polished steel, brass bearings and gears, ceramic spark-plug insulators, and restrained painted surfaces. Preserve small bevels, cooling-fin edges, and clearances around moving linkages.

Animate all 28 cylinders through a synchronized 720-degree four-stroke cycle. Drive the crankshaft, connecting rods, pistons, valves, rocker arms, springs, propeller, and supercharger from a shared phase. For this illustrative mechanism, show the propeller turning at 0.375 times crankshaft speed, the cam rings turning in the opposite direction at one-sixth speed, and the supercharger at 6.375 times speed. Indicate firing with brief orange rings and a restrained glow. Color the cylinder charge blue for intake, dark gray for compression, orange for power, and gray for exhaust, with optional airflow arrows. 把展品换成一台涡轮喷气发动机：进气口、多级压气机、燃烧室、涡轮与尾喷管沿轴线排布，同样支持剖切与部件特写。动画展示气流从吸入、压缩、燃烧到喷出的全过程，燃烧室用橙色高亮，尾喷口有轻微热流扭曲效果。保留转速调节与同步工程图表。 Surround the model with synchronized diagrams for the master-rod mechanism, planetary reduction, power curve, firing order, relative rotational speeds, and valve timing. Keep illustrative thermodynamic readings clearly identified as such. Provide an engine-speed control from 200 to 3000 RPM, slow-motion playback, run and pause, 15-degree stepping, and a scrubber covering the full 720-degree cycle. Dragging the valve-timing chart should also change the engine phase.

Let users select any of the 28 cylinders from the firing-order strip or directly on the model, track its cycle, isolate it with its linkage and cam ring, and open a close-up. Provide hero, front, side, and connecting-rod detail views; the linkage close-up should automatically slow playback. Offer solid, transparent-shell, and half-section modes, plus switches for labels, charge visualization, airflow arrows, isolation, and charts. Keep fine leader-line labels readable and clear of the engine and panels, with smooth camera transitions and responsive framing.
