This engine was the first Soviet twin-spool turbojet. It was first run in early 1956 [1] and was later employed in some variants of the Yakovlev Yak-26 and Yakovlev Yak-27, as well as the Yak-28. [2] The R-11's basic design was very successful and it was later developed into the Tumansky R-13 and Tumansky R-25 along with the experimental ...

The AN/URM-25 was part of a series of vacuum tube-based signal generators built for the U.S. military in the early Cold War-era.. Today they are collected and used by vintage amateur radio and antique radio enthusiasts who say they provide reasonably high accuracy and stability for a low cost, with build quality reflecting tough military construction requirements and standards.
Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout starts with the process of schematic capture. The result is what is known as a rat's nest. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes.
75 mm howitzer of the 1st Airlanding Light Artillery Regiment in action in Italy. 75 mm pack howitzer on carriage M1, supplied to Chinese forces. Two major lend lease recipients of the M1 were United Kingdom (826 pack howitzers) and China (637 pack howitzers and 125 field howitzers). 68 pieces were supplied to France, and 60 to various ...
The maximum thrust was 7,500 kilograms force (73.5 kN, 16,500 lbf) dry and 11,200 kilograms force (110 kN, 24,700 lbf) with afterburner. This thrust enabled the Mikoyan-Gurevich MiG-25, with two engines, to reach Mach 3.2, although the engines had to be scrapped after a flight to Mach 3.2. The engine had a very high fuel consumption, especially ...
The AN/TPS-75 radar antenna packed on a 5-ton truck. The AN/TPS-75 is the primary transportable Aerospace Control And Warning (AC&W) radar used by the United States Air Force. [n 1] [1] The TPS-75 is capable of transmitting 5-Megawatts of power. (Although 5-Megawatts is almost never achieved; realistically it is approx 2.8 Megawatts)
The Army never acquired the ARA 1.5 to 3.0 MHz receiver, nor the ATA 2.1 to 3.0 MHz transmitter. Initially, it did not acquire the 3.0 to 4.0 MHz transmitter, nor the 0.52 to 1.5 MHz receiver, but the need to communicate on the common civil airfield frequency of 3.105 MHz plus the anticipated USAAF use of the AN/ARR-1 homing adapter (see below ...
