| edtherenderman | Cleveland Westland Whirlwind | Build | 28-Jan-22 08:29 |  | | Views : 239 | | Presenting the design for the fowler flaps. I looked on line for how they work on real aircraft and studied what available pictures I could find for the Whirlwind and came up this. There are two rails, one that runs along bottom of the wing, and one along the top. The flap has a pivot point in the leading edge that runs along the bottom rail. There is a bracket that is set into the flap about 1/3 of the way back from the trailing edge that has a pivot point in the flap and runs along the upper rail. As the flap extends back, the closing distance between the two rails forces the flap down. |

| edtherenderman | Cleveland Westland Whirlwind | Build | 23-Jan-22 20:04 |  | | Views : 259 | | Port side wing. Standard construction. I tried to use the 110lb Card Stock to cover the outer panel of the wing, but did not like how it was laying down, so switched back to 1/32” balsa sheet. I think the balsa gives a little more room for flex and can deal with the slight irregularities in the ribs. I’ve not covered the inner section because I’m thinking of putting working Fowler Flap on the model. These are what the original aircraft had. Still thinking about it because it will require a major modification to both engine nacelles and 3D printing the flaps and hardware. |
| edtherenderman | Cleveland Westland Whirlwind | Build | 23-Jan-22 20:00 |  | | Views : 303 | | Empennage! The fin, rudder, horizontal stab, elevator and center section that they all connect to. The center section on the original model was to be carved from balsa block, but I 3D printed it instead. Using bamboo skewers to attach all parts. Elevator and bottom rudder hinge is made using .40 mm styrene shaped to fit into slots cut in leading edges with pins that will slot into the trailing edges of the fin and Horizontal Stab. Horizontal Stabs are covered in 110 lb card stock CAed in place. |
