Curtiss HA-21918 |
FIGHTER | Virtual Aircraft Museum / USA / Curtiss |
The third HA float fighter prototype embodied considerable redesign as the HA-2. Powered by a 12- cylinder Liberty 12 water-cooled engine, like the preceding prototypes, the HA-2 had longer-span wings of marginally increased chord and gap, the upper wing being raised clear of the fuselage, the decking of which was lowered. The radiator was redesigned, but cooling problems were encountered and although the HA-2 proved more docile than the lighter HA-1, it possessed insufficient promise to warrant further development.
