Storage Resource Broker (SRB) is data grid management computer software used in computational science research projects. SRB is a logical distributed file system based on a client-server architecture which presents users with a single global logical namespace or file hierarchy. [1]
[10] The SRBs were the largest solid-propellant motors ever flown and the first of such large rockets designed for reuse. [11] Each is 149.16 ft (45.46 m) long and 12.17 ft (3.71 m) in diameter. Each SRB weighed approximately 1,300,000 lb (590 t) at launch. The two SRBs constituted about 69% of the total lift-off mass.
[citation needed] Reusability of components across multiple flights, as in the Shuttle assembly, also has decreased hardware costs. [5] One example of increased performance provided by SRBs is the Ariane 4 rocket. The basic 40 model with no additional boosters was capable of lifting a 4,795 lb (2,175 kg) payload to geostationary transfer orbit. [6]
The SRMU is a three-segment solid rocket motor. Each segment has a casing wound from graphite fibre composite and an insulation system of EPDM rubber and kevlar. [1] The casing is filled with a fuel grain composed primarily of ammonium perchlorate and aluminium, joined by a HTPB binder. [2]
Booster separation motors fire. The booster separation motors or BSMs on the Space Shuttle were relatively small rocket motors that separated the reusable solid rocket boosters (SRB) from the orbiter after SRB burnout.
The Castor 1 was first used for a successful suborbital launch of a Scout X-1 rocket on September 2, 1960. [4]It was 19.42 feet (5.92 m) long, 2.6 feet (0.79 m) in diameter, and had a burn time of 27 seconds.
NixOS is a free and open source Linux distribution based on the Nix package manager.NixOS uses an immutable design and an atomic update model. [6] Its use of a declarative configuration system allows reproducibility and portability.
Bank, pit bank or pit brow. The bank, pit bank or pit brow is the area at the top of the shaft. [3]Banksman or banker. A banksman, banker, hillman or browman works at the pit bank to dispatch the coals, and organise the workforce.
