![]() 0,1s turn time (only when stock, its the exact same when full upgraded) 7 km/h top speed ( stock : 609 to 602, full upgraded : 650 to 642) Ingame F IX to F IXc performance loss (2 Hispano Mk. Im sorry that i couldnt find any source that include performance loss between setup, but i believe it should be similar as the F Mk IX to F Mk IXc, since there is no exact difference between gun apart from maybe different ammo count 4.4 The moment effect due to undercarriage retraction is 3150 in/lb. 4.3 A further forward centre of gravity of 1.9" aft may be obtained when the aeroplane is in a light loaded condition of "TARE" weight plus a light pilot of 170 lb. by the expenditure of Browning and Hispano gun ammunition and the consumption of fuel but leaving a supply sufficient for 1.2 hour's running of the engines at maximum power permissible at ground level. The forward limit is obtained from Load 1. ![]() 4.2 The centre of gravity range due to dissipation of load is 4.0" aft to 4.8" aft, Load 2. 4.1 The centre of gravity with the above loads measured parallel to the datum line and relative to the datum point (See Fig.1) are: Load 1. Vc airframes, the undercarriage indicator pins were not used on this or any of the later Spitfire marks.Įven though Spitfire Mk. Vc has 4 Hispano Mk. The wing structure was stressed for provision of hardpoints outboard of the wheel wells capable of taking a 250 lb (113 kg) bomb under each wing.Īpart from early Spitfires Mk. Also, the lower surface of the wing no longer had the gun-bay heating vents outboard of the gun bays and the retractable landing lights were no longer fitted. ![]() The inner machine gun bays in C wing were moved outboard to between ribs 13 and 14. In such circumstances, the very large blister on top of the wing was not required and a new, more streamlined cannon breech cover was provided, with narrow blister fairing over the inboard cannon position and flat surface over the second, unused cannon bay. Later on, production aircraft carried the two 20mm Hispanos and four Brownings. In field conditions, it was often sufficient with two cannon armament and many of the four-cannon Spitfires were converted to fly with either outboard or inboard pair of Hispanos, or else converted to B-standard armament. Vc, such as those which were transported to Malta were factory-fitted with four cannon. Initially a single wide blister was incorporated that covered both motors. The redesigned upper wing gun bay doors incorporated blisters to clear the cannon belt feed motors. ![]() Spitfire Mk Vc with Type B armament setup at FHC The fairings over the Hispano barrels were shorter and there was usually a short rubber stub covering the outer cannon port when not in use.Ĭomparison of armament layout Type A ( Middle ), Type B ( Top ) and C ( Bottom ) wings on the Spitfire Mk V The Hispano Mk II cannon fitted in all cases were now belt-fed from box magazines (the Chattellerault system) allowing to double the ammunition supply to 120 rounds per gun. The revised, strengthened undercarriage legs were raked 2 inches (5.08 cm) further forward, making the Spitfire more stable on the ground and reducing the likelihood of the aircraft tipping onto its nose. The undercarriage mountings were redesigned and the undercarriage doors were bowed in cross section allowing the legs to sit lower in the wells, eliminating the upper-wing blisters over the wheel wells and landing gear pivot points. Called “universal wing”, this wing was structurally modified to reduce labour and manufacturing time and allow mixed armament options A or B type armament or a new, yet heavier combination of four 20 mm Hispano cannon. ![]()
