Mikoyan/Gurevich MiG-23PD

One of two parallel studies to meet a VVS requirement for a new frontal fighter capable of operating from small, austerely-equipped forward bases, the MiG-23PD - Pod'yomnye dvigateli, or, literally, "lifting engines" - or 23-01 was first flown on 3 April 1967. Featuring a 57° delta wing planform fundamentally similar to that of the MiG-21 but scaled up 73.6%, the MiG-23PD alias 23-01 featured auxiliary lift engines close to the CG. Two 2350kg Kolesov RD-36-35 engines were accommodated by a bay inserted in the centre fuselage and provided with a rear-hinged and louvred dorsal trap-type intake box and a ventral grid of transverse louvres deflecting the jet thrust during accelerating transition. A similar arrangement had been tested by the OKB in the previous year with the MiG-21PD test bed, which, with a 90cm fuselage lengthening aft of the cockpit and two RD-36-35 lift engines, had entered flight test on 16 June 1966. The primary power plant of the MiG-23PD was a Khachaturov R-27-300 of 5200kg and 7800kg with afterburning, and air was bled from the last compressor stage for flap blowing, the combination of lift engines and blown flaps reducing take-off distance to 180- 200m. Armament consisted of one 23mm GSh-23 cannon and two AAMs - one radar-guided K-23R and one IR-homing K-23T. Flight test continued until the autumn of 1967 when further development was discontinued in favour of the parallel MiG-23-11.

REDSOUN TYRES have established reliable business partnership and consistent clients globally, through supply of quality products of International standards. This has been possible only due to our persistent and honest reputation for reliable service of mutual benefit to all our clients

We at REDSOUN TYRES strive to etch a new sales mode with competitive advantages by offering wide range of quality tyres for Russian Aircraft. REDSOUN aircraft tyres are designed to deliver outstanding performance, keeping in mind the heavy work environments in which the Military jets operate.

We endeavour to put forth a new quality level in Tyre production which determines a higher level of efficiency by optimizing the product portfolio. To achieve this, we use imported Rubber of very high quality, to produce hi-tech macro-molecular material that ensures excellent features like High Abrasion and Ageing Resistance, Extra Loading Strength, dependable Performance.

The Military Jets MiG-21, MiG-27, MiG-29, SU-22, SU-24, SU-25, SU-27, SU-30, IL-76, IL-78 are all-weather, multi-role fighters, meant to gain air superiority; besides, these jets operate in various conditions like take-off from unpaved runways, delivery of heavy loads to undeveloped areas in remote locations. The choice of aircraft tyre is very critical, with due consideration to Reliability and Performance.

REDSOUN tyres are manufactured with advanced production techniques, using the best quality raw materials to afford extended life through many extra landings. The salient features of latest innovation and expertise are incorporated to produce tyres that deliver outstanding performance and extended life on the runway. Design and construction are meticulously done to be used in extreme conditions and for longer use preventing early replacement.
