General info

Flight performance

Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

Pros and cons

Pros:

• Ludicrously powerful armament layouts with decent ammo capacities
• Both the 37 mm cannons and 45 mm cannons have high muzzle velocity are quite accurate
• Firing the guns barely slows the aircraft down
• Reasonable manoeuvrability for a twin-engined fighter bolstered by leading-edge slats
• Decent speed, but lower than most fighters it will encounter
• Acceptable acceleration for a twin-engined fighter
• All armaments centred in or near the nose, resulting in little need for convergence adjustments, except for long-distance shots
• Can mount bombs and rockets for ground-pounding
• Premium rewards

Cons:

• Slower than contemporary aircraft
• Lack of bulletproof glass makes the pilot prone to snipes, also vulnerable to head-on attacks
• Extremely prone to fires

History

The TIS A (and the improved MA) were designed to a 1938 specification for a heavy fighter - but work did not begin until 1940 due to resources being devoted to the I-180 and SPB projects.

The TIS A was an all metal monocoque monoplane with a very heavy forward facing armament of some mix of 2 x 37mm, 2 x 20mm cannon; and 2 x 12.7mm UB + 4 x 7.62mm ShKAS machine guns, or 6 x 7.62mm ShKAS machine guns - sources vary on the exact nature of armament for the prototype. The single rear gunner had 2 ShKAS machine guns - 1 mounted to fire from a dorsal position, the other mounted to shoot through a ventral hatch. It was fitted with Mikulin AM-39 engines, but these had protracted development problems - they were unreliable and vibrated above 5000m altitude.

By 1942 flight testing showed several problems, and a major redesign was conducted - radiators were moved to the wings, the machine guns in the nose were replaced by 2 x ShVAK 20mm cannon, and 2 x 45mm 11P guns were fitted in the wing roots. The gunner's 2 x ShKAS were replaced by a single 12.7mm UBT machine gun. Engine reliability was not improved, so AM-38F engines (as fitted to Il-2's) were fitted instead - and these had much lower output resulting in predictably lower performance, especially at higher altitudes due to the AM-38's single stage supercharger optimised for lower altitudes.

This configuration was renamed the TIS-MA.

Flight testing of the TIS-MA from June-September 1944 found it performed as expected with the new engines - being generally disappointing at altitude. Calculations showed much better performance if the desired AM-39's could be fitted. However fate intervened - Polikarpov died on 30 July of stomach cancer, and when the TIS-MA crashed on 15 September it spelled the end of the program - his design bureau was being shut down and none of the others could or would take it on.
