[3] [4] The vehicle's armor was up to 12 mm thick, and the vehicle weighed 10 short tons (9.1 t). [1] The suspension was leaf spring on the front axle and vertical volute spring for the tracks. A 386-cubic inch (6.330 cc) White 160AX, 128-horsepower (95 kW), 6-cylinder gasoline engine gave the M15 a power-to-weight ratio of 15.8 horsepower per ...
In 2023, the aircraft received its official designation as X-65. [4] In January 2024, DARPA and Aurora started CRANE Phase 3, building the first full-scale X-65 aircraft using active flow control actuators for primary flight control. [5] [6] The 7,000-pound X-65 will be rolled out in early 2025 with the first flight planned for summer of 2025. [7]
The pneumatic control signals are traditionally based on a pressure range of 3–15 psi (0.2–1.0 bar), or more commonly now, an electrical signal of 4-20mA for industry, or 0–10 V for HVAC systems. Electrical control now often includes a "Smart" communication signal superimposed on the 4–20 mA control current, such that the health and ...
The 22.5 cm Minenwerfer M 15 was a heavy mortar used by Austria-Hungary in World War I. [1] It was developed by Böhler as an alternative to the German Ehrhardt 25 cm schwere Minenwerfer which Böhler was having problems building under license. It was a muzzle-loading, smooth-bore mortar that had no recoil system whatsoever.
[4] [5] Horton is credited for developing the first fluid amplifier control device and launching the field of fluidics. [6] In 1961, Horton, Warren, and Bowles were among the 27 recipients to receive the first Army Research and Development Achievement Award for developing the fluid amplifier control device.
[1] The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero."

However, in 1926 there was an urgent requirement for fifteen more powerful 4-4-0 locomotives for the London-to-Folkestone express trains. Maunsell did not rebuild the L class, as the locomotives were still relatively new and useful in their current form, but amended Wainwright's drawings to form his own L1 class, and supplied them to the North ...
[1] Flow-control structures are known to have existed for thousands of years. Some built by the Chinese have been in continuous use for over 2,000 years. The Chinese used these structures to divert water to irrigate fields and to actually deposit silt in specific areas so that the channels were not blocked by silt build-up.
