An 8¿lobed finocyl grain with tapered fins gives a large initial surface area for rapid pressurization and a progressive¿neutral burn over ~110-120 s; the grain is carbon¿fiber reinforced to withstand up to 12 MPa. A flex nozzle with 0.61 m throat, 15:1 expansion (exit Ø 2.36 m), and a carbon¿carbon throat coated with ZrC is optimized for seälevel\/vacuum. Predicted performance: 5,800 kN thrust, exhaust velocity ¿2,714 m\/s, Isp ¿277 s, mass flow ¿2,138 kg\/s.","brand":"LAP LAMBERT Academic Publishing","offers":[{"title":"Default Title","offer_id":53795770302806,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.momoxbooks.com\/products\/prasanth-s-optimization-of-grain-and-nozzle-geometry-in-solid-rocket-booster-gslv-9786209083624","provider":"momoxbooks","version":"1.0","type":"link"}
