AR-1 (rocket Engine)
The Aerojet Rocketdyne AR1 is a thrust RP-1/LOX oxidizer-rich staged combustion cycle rocket engine project. The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. By 2018, the USAF had committed of government funding to develop the engine and build an initial engine prototype, while Aerojet will put of private capital into the project through the prototype build. , there have been no plans to take the AR1 to full production. History Aerojet Rocketdyne proposed in 2014 to "lobby the government to fund an all-new, U.S.-sourced rocket propulsion system." In June 2014, Aerojet initially projected it would cost under per pair of engines, not including the up to estimated development cost to be funded by the government. Later in 2014, the US Congress passed a law requiring the US Air Force to "develop a new propulsion system by 2019 to replace the RD-180 engine" that powers Atlas V used by United Launch Alliance (ULA).

Arkansas's 1st Congressional District
Arkansas's 1st congressional district is a U.S. congressional district in eastern Arkansas that elects a representative to the United States House of Representatives. It is currently represented by Republican Rick Crawford. With a Cook Partisan Voting Index rating of R+21, it is the most Republican district in Arkansas, a state with an all-Republican congressional delegation. Geography 2003–2013 Before the 2010 census, the 1st district represented portions of northeastern Arkansas, encompassing the counties of Arkansas, Baxter, Clay, Cleburne, Craighead, Crittenden, Cross, Fulton, Greene, Independence, Izard, Jackson, Lawrence, Lee, Lonoke, Mississippi, Monroe, Phillips, Poinsett, Prairie, Randolph, Saint Francis, Searcy, Sharp, Stone, and Woodruff. 2013–2023 The district was redesigned to take in additional counties in the southeastern portion that were part of the 4th district which in turn took the entire eastern Arkansas border. It is now more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkansas Highway 1
Highway 1 (AR 1, Ark. 1, and Hwy. 1) is a north–south state highway in east Arkansas. The route of runs from US Route 278 (US 278) in McGehee north to Supplemental Route BB at the Missouri state line. One of the original 1926 state highways, Highway 1 has remained very close to its original routing. The highway contains an overlap of approximately with U.S. Route 49. Route description McGehee to Back Gate Arkansas Highway 1 begins at U.S. Route 278 in downtown McGehee and runs northwest (along the Union Pacific Railroad tracks) for three blocks before turning northeast at an intersection with AR 159. The highway continues across US 65/US 165 and exits town in a northeastern direction, passing McGehee High School. AR 1 meets Arkansas Highway 4, which runs south to Arkansas City before curving north to Rohwer, which was a Japanese American internment camp during World War II. AR 1 passes the Kemp Cotton Gin Historic District, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Research
Acoustic Research was a Cambridge, Massachusetts-based company that manufactured high-end audio equipment. The brand is now owned by VOXX. Acoustic Research was known for the AR-3 series of speaker systems, which used the acoustic suspension woofer of the AR-1 with newly designed dome mid-range speaker and high-frequency drivers. AR's line of acoustic suspension speakers were the first loudspeakers with relatively flat response, extended bass, wide dispersion, small size, and reasonable cost. Company history Acoustic Research, Inc. (“AR”) was founded in 1954 by audio pioneer, writer, inventor, researcher and audio-electronics teacher Edgar Villchur and his student, Henry Kloss. AR was established to produce the $185 () model AR-1, a loudspeaker design incorporating the acoustic suspension principle based on , granted to Edgar Villchur and assigned to Acoustic Research in 1956. Edgar Villchur's technical innovation was based on objective testing and research, most of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Suspension
Acoustic suspension (air suspension, closed box, sealed box) is a method of loudspeaker cabinet design and utilisation that uses one or more loudspeaker drivers mounted in a sealed box or cabinet. Acoustic suspension systems reduce bass distortion that can be caused by stiff motor suspensions in conventional loudspeakers. A compact acoustic suspension loudspeaker was described in 1954 by Edgar Villchur, and it was brought to commercial production by Villchur and Henry Kloss with the founding of Acoustic Research in Cambridge, Massachusetts. In 1960, Villchur reiterated that: ''The first aim of the acoustic suspension design, over and above uniformity of frequency response, compactness, and extension of response into the low-bass range, is to reduce significantly the level of bass distortion that had previously been tolerated in loudspeakers. This is accomplished by substituting an air-spring for a mechanical one.'' Subsequently, the theory of closed-box loudspeakers was extensive ...

USS Medusa (AR-1)
USS ''Medusa'' (AR-1) was the United States Navy's first purpose-built repair ship. She served in the U.S. Navy from 1924 to 1946. Technical characteristics Authorized as part of the naval programs of 1916 and 1918, ''Medusa'' was laid down at the Puget Sound Navy Yard, Bremerton, Washington, on 2 January 1920. She was launched on 16 April 1923, sponsored by Mrs. Burns Poe, and commissioned on 18 September 1924. ''Medusa'' was the first U.S. Navy ship designed as a fleet repair ship for major repairs beyond the fighting ship’s own capabilities but which must be accomplished without the benefit of visiting a shipyard. Prior to the commissioning of ''Medusa'', U.S. Navy repair ships had been converted for that purpose. As the U.S. Navy began to grow in size during the World War I years, it was felt that such conversions would prove inadequate for the Navy's needs. The Department of the Navy designed ''Medusa'' with an eye toward at least equalling the repair facilities of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AR-1 (multiple Rocket Launcher)
The BM-30 ''Smerch'' ( rus, Смерч, "tornado", "whirlwind"), 9K58 Smerch or 9A52-2 Smerch-M is a heavy self-propelled 300 mm multiple rocket launcher designed in the Soviet Union. The system is intended to defeat personnel, armored, and soft targets in concentration areas, artillery batteries, command posts and ammunition depots. It was designed in the early 1980s and entered service in the Soviet Army in 1989. When first observed by the West in 1983, it received the code MRL 280mm M1983. It continues in use by Russia; a program to replace it with the 9A52-4 Tornado began in 2018. Operational history The first confirmed combat uses of the Smerch were in two war zones in 2014. Syrian military forces used the system against rebel forces during the Syrian civil war, including in fighting in Jobar. It was also used by Russia-backed militants to deliver explosive and cluster munitions to Ukrainian military positions and likewise by the Ukrainian Army. Several have bee ...
