Creation History
Soon after the development of the S-1 and T-3 planes - the first for the restored Sukhoi Design Bureau - in the general types department, a preliminary design of the P-1 aircraft intended for operation in the Uragan-1 interception system began. The car was developed on the basis of a decision of the Council of Ministers from the end of 1954. The main option was a two-seat aircraft, although a single-seat option was also considered [1] .
Initially, three engine options were considered for installation on an interceptor: one AL-11 ; one R15B-300 or two AL-9 , however, with the exception of the R15B-300, the remaining options disappeared by themselves, since they did not leave the “paper stage” until the end of the tests. However, even the R15B-300 was very late, so the AL-7F already in production was installed on the plane. The preliminary design of the P-1 provided for a frontal air intake with the placement of one of the radar antennas in the influx above it of the experimental T-3 type . However, due to the size of the radar, such a solution could not be applied, so the P-1 was the first Sukhoi Design Bureau aircraft with lateral air intakes. [1] At the leading edge of the wing of a triangular shape, a characteristic “ledge” (similar to that on the T-3), recommended by TsAGI, stood out. The fuel was located in two fuselage and four wing tanks with a total capacity of 2410 liters. Together with a suspension tank with a volume of 950 l, the fuel reserve was supposed to provide a range of 1400 and 2000 km, respectively [1] .
The prototype was built in June 1957 , by June 10 it was moved to the aerodrome LII. The first flight on the P-1 took place on July 12 in Zhukovsky (test pilot N.I. Korovushkin). Then, pilot of the LII E.V. Yelyan joined the tests. Until November 26, the aircraft made four test flights [1] . At the same time, three aircraft began to be built at plant No. 153 in Novosibirsk under the planned R15B-300 turbojet engines. However, at first the Uragan-1 interception system did not pass, then work on K-7 missiles was stopped in favor of K-8. In 1958, P.O. Sukhoi proposed the P-2 low-altitude interceptor variant, in which the P-1 was equipped with Panther radar and two K-9 air-to-air missiles. However, for the automated guidance of the P-2 with the help of the Air-1 system under development, a need arose for a repeater aircraft. In addition, Sukhoi Design Bureau began designing the T-37 heavy interceptor. This circumstance put an end to the history of P-1; The experimental aircraft was used for some time as a flying laboratory, then it was scrapped.
armament
In both versions, the interceptor was equipped with underwing suspension points. In the P-1 variant, the combat load of the aircraft varied. Suspension was provided for two K-7 missiles, or two ARS-212 and fifty ARS-57 or 32 turbojet TRS-85 stabilized by rotation [2] .
Avionics
The aircraft control system included the AP-28 autopilot . Guidance interceptor was to be carried out in an automated mode. In addition, the equipment included the RV-U radio altimeter , GIK-1 gyrocompass , RSIU-4 transmitter, SPU-1 intercom, and some other equipment [3] .
Modifications
- P-1 is the basic version.
- P-2 - a variant of a low-altitude interceptor with Panther radar and K-9 missiles. It was equipped with two VK-11 engines [2] .
Aircraft Rating
P-1 is considered as an interceptor quite advanced for its time, resembling F-104B with technical solutions.
However, an experienced P-1 with a lower thrust engine, devoid of radar, guidance and armament equipment, could only determine takeoff and landing characteristics and stability and controllability parameters in some modes, as well as evaluate the platform itself. However, in the face of a disruption in the supply of planned engines and weapons, the aircraft was not needed either by the customer or Sukhoi Design Bureau.
