![]() ![]() The system had been experimentally flown in other aircraft, but these were all biplanes, and the condensers and collector tank for the condensed water were all mounted in the upper wing. The evaporative cooling system used by the Goshawk involved allowing the cooling water to reach a temperature greater than 100 ☌ without boiling by keeping it under pressure while circulating through the engine: this superheated water was then allowed to boil off by releasing the pressure, the resulting steam then being cooled in a condenser, collected as water and then recirculated through the engine. Behind the main spar the wing was fabric-covered. The wing was of unusual construction, having a single main spar, forward of which the condensers of the engine cooling system formed the entire leading edge of the wing, the combination of the two producing a 'D-box' spar of great torsional rigidity. ![]() The fuselage was of monocoque construction, with one pair of guns mounted either side of the cockpit and the other pair in the 'trouser' fairings of the undercarriage. The cockpit was open, and further wind-tunnel tests were also carried out on a full-size model of the cockpit area to ensure that the pilot would not be subjected to undue buffeting. These tests also revealed a lack of directional stability: Mitchell accordingly enlarged the fin area. The gull wing configuration was chosen in order to shorten the undercarriage legs and so reduce drag, but since this configuration was known to be liable to produce problems with lateral stability an extensive programme of wind-tunnel testing using models was carried out before arriving at the final design. Mitchell, Supermarine's designer, came up with a clean-looking inverted gull-wing monoplane with a fixed undercarriage powered by the 600 hp Goshawk II. In addition, privately funded submissions for the competition were encouraged. Of the many proposals submitted by manufacturers, three were selected for official development as prototypes, the Supermarine 224 among them. Although the use of any power plant was permitted, the Air Ministry did express a preference for the evaporatively cooled Rolls-Royce Goshawk then being developed. The importance of a good view from the cockpit was made clear. Specification F.7/30, which was formally issued to the aircraft industry in October 1931, called for an all-metal day and night fighter armed with four machine guns, a high top speed and rate of climb, and a landing speed of less than 60 mph. Mitchell learnt lessons from its failure that were to contribute greatly to his success with the Supermarine Spitfire. It was powered by the Rolls-Royce Goshawk engine, which used an experimental evaporative cooling system, and problems with this system, combined with its disappointing performance, led to it being rejected, a contract for production aircraft eventually going to the Gloster Gladiator. Mitchell at Supermarine in response to Air Ministry Specification F.7/30, which sought a fighter for introduction to succeed the Gloster Gauntlet. Here’s the Youtube teaser for it if you’re interested.The Supermarine Type 224 was an inverted gull-wing monoplane fighter aircraft designed by R.J. There’s a bunch of other stuff, but this is just a taste.īut it will be cool to finally play it when it does, as I haven’t had the chance to play it on the table yet. There are also birds with yellow game end powers (like the Little Pied Cormorant above). Nectar can be used as a wild resource, but it also counts as points when you consume it. There’s the wild resource, Nectar and new player boards that will accommodate it. The Oceania expansion adds a host of new birds and gameplay mechanics to the game. Another expansion, and this time it’s one I haven’t played before. Like the email from Monster Couch that says the Oceania expansion is coming soon to their digital implementation of Wingspan! It’s nice when you look at your email inbox and find some welcome news instead of the usual spam and people bothering you about things you don’t care about.
