The Algol family of solid-fuel rocket stages and boosters built by Aerojet (now Aerojet Rocketdyne) and used on a variety of launch vehicles. It was developed by Aerojet from the earlier Jupiter Senior and the Navy Polaris programs. 〔(【引用サイトリンク】title=Scout Launch Vehicle Program )〕 Upgrades to the Algol motor occurred from 1960 till the retirement of the Scout launch vehicle in 1994. Solid propellant rocket stage. Loaded/empty mass 10,705/1,900 kg. Thrust 470.93 kN. Vacuum specific impulse 236 seconds. Variations included Algol I, I-D, II, II-A, II-B and possibly others. Another popular rating was 40KS-115,000 (52,000 kgf for 40 seconds), also known as Senior. They were initially developed as the first-stage motor of the Scout rocket. The design was based the Polaris, a sea-to-air missile developed for the United States Navy at the Jet Propulsion Laboratory.〔(【引用サイトリンク】title=NASA'S SCOUT LAUNCH VEHICLE )〕〔(【引用サイトリンク】title=SERGEANT )〕 == Algol 1 (XM-68) == ; Algol 1 (XM-68) : This rocket design started as the Polaris test motor, 31 feet in length with a 40 inch (1.02m) diameter steel case, and 86,000 lb. of thrust. : The eventual UGM-27 Polaris A-1 was larger, 28.5 feet (8.5m) in length and 54 inch (1.4m) in diameter. : The Algol 1 was first used for a successful suborbital launch of a Scout X-1 rocket on September 2, 1960.〔(【引用サイトリンク】 TSE - Scout )〕 This rocket started as a UGM-27 Polaris test motor with a 40 inch diameter, which at the time was the largest solid motor ever tested. It had a nominal performance rating of 45 seconds duration and 45,000 kgf thrust. :It was long, in diameter, and had a burn time of 27 seconds. Scaled up to 1.02m diameter (40 inches). Later versions for Scout D scaled to 1.14m (45 inches) ; Algol 1-A : Used on the Scout X (Cub Scout) test flight flown April 18, 1960. served as prototype vehicle for eventual Scout rocket. ;Algol 1-B : Used on Scout X-1, RM-89 Blue Scout I, and RM-90 Blue Scout II. ;Algol 1-C : Used on the Scout X-1A. After this single flight, the Scout X-2 with Algol 1-D replaced this prototype. ; Algol 1-D : Used with Scout X-2, Scout X-2M and Little Joe II. Solid rocket stage. 440.00 kN (98,916 lbf) thrust. Mass 10,700 kg (23,589 lb). : It was first used on the Scout X-2 on March 29, 1962. It continued to be used on Scout X-2 and Scout X-2M launches (4) until 1963. : Algol 1-D was first used on the ()] Little Joe II Qualifying Flight in 1963. • May 13, 1964 – Algol Boosts Little Joe II A-001 flight. An Aerojet-built Algol 1D heavy-duty rocket motor performed successfully for the 36th consecutive time on May 13, 1964 as it carried a NASA Little Joe II spacecraft on the Apollo program A-001 test flight. Averaging 96,650 pounds thrust, the Algol 1D was the largest solid rocket motor flying in non-military space programs. Test hardware on May’s successful Apollo test flight included: an unmanned instrumented command module, service module, launch escape system and the Little Joe II launch system. Algol engine used on Little Joe II Thrust: 465 kN each Length: 9.1 m Diameter: 1 m Weight full: 10,180 kg Weight empty: 1,900 kg Fuel: solid Burn time: 40 s Status: Retired 1966. Gross mass: 10,700 kg (23,500 lb). Unfuelled mass: 1,200 kg (2,600 lb). Height: 9.40 m (30.80 ft). Diameter: 1.02 m (3.34 ft). Thrust: 440.00 kN (98,910 lbf). Burn time: 44 s.
