The prompt
# Hydraulic Aircraft Wing and Flaperon CAD Model Create a detailed, parametric 3D CAD model of a small aircraft wing with a hydraulically actuated movable flaperon. Follow the supplied reference sketch. ### 1. Wing Geometry - Chord: 240 mm. - Wingspan: 120 mm. - Maximum thickness: 48 mm. - Movable rear flaperon: 60 mm chord. - Rounded leading edge, curved upper surface and relatively flat underside. - Separate movable flaperon hinged along the wingspan near the upper rear edge. - Flaperon must rotate approximately 30° downward and return to alignment. ### 2. Hydraulic System Design the mechanism around two real commercially purchased syringes: - Internal actuator: InJ/Light 60 ml syringe. - External controller: KL MED 20 ml syringe. **IMPORTANT: DO NOT MODEL THE SYRINGES AS PRINTABLE COMPONENTS.** Instead, create hollow mounting compartments and removable retaining clips. For preliminary dimensional planning, use: - 60 ml syringe: approximately 29 mm barrel diameter and 125 mm barrel length. - 20 ml syringe: approximately 21 mm barrel diameter and 103 mm barrel length. These are generic reference dimensions, NOT verified manufacturer measurements. Make all syringe dimensions adjustable through parameters, allowing corrections after physical measurement. Position the internal syringe horizontally, with its nozzle facing the leading edge and plunger facing the flaperon. Provide sufficient clearance for plunger movement. Create an external removable cradle for the 20 ml syringe, keeping its plunger accessible. ### 3. Linkage and Tubing Connect the internal syringe plunger to a flaperon-mounted control horn using a short pivoting mechanical linkage. Include suitable pivot holes, hinge supports, connecting pins and mechanical clearances. The external syringe must connect to the internal syringe through real flexible tubing. DO NOT MODEL tubing, electrical wires or cables as printable components. Instead, provide accessible tubing channels and openings. ### 4. Cutaway Design Include a removable side panel revealing the internal syringe compartment, retaining clips, linkage, control horn and hinge mechanism. Keep the wing, flaperon, linkage, hinge, pins, mounting clips and external cradle as separate printable components. ### 5. Printing and Functionality Available printer build volume: 256 × 256 × 256 mm³. Ensure every printable component fits within this envelope. Include practical assembly clearances, removable mounting features and adequate structural walls. Make the design fully parametric, particularly syringe dimensions, plunger travel, linkage length and hinge position. Prioritise reliable movement, easy assembly and visibility of the hydraulic mechanism. This is an educational school demonstration, not a flight-certified aircraft component.
