“…Selain itu, viskositas juga semakin tinggi ketika kebutuhan akan isian padatan dalam propelan meningkat untuk kenaikan impuls spesifik (Isp). (Dey, Athar, Sikder, & Chattopadhyay, 2015;Muthiah, Somasundaran, Verghese, & Thomas, 1989;Remakanthan, Kk, Gunasekaran, Thomas, & Thomas, 2015).…”

“…Untuk cairan Newtonian, yang mana besarnya viskositas tidak tergantung pada gaya geser, tegangan geser (shear stress), τ, berbanding lurus dengan laju geser (shear rate), γ, dan viskositas, µ, seperti dikemukakan pada Persamaan 1-1 (Chhabra RP & Richardson JF, 2008). (Muthiah et al, 1989). Di sisi lain, plasticizer energetik dapat berbasis Azido, ester nitrat, N-Nitramine, Nitro aromatic, Oxetane, Nitro aliphatic dan GLYN dimer (Manu, 2009).…”

“…Efek ini pun masih ada saat isian cair telah bercampur dengan serbuk aluminium dan partikel Ammonium perklorat (AP) baik bimoda maupun trimoda. Lebih lanjut, DOA diketahui kompatibel terhadap slurry dengan komposisi yang mengandung AP bimoda sebaik IDP (Gupta, Kumar, & N, 2014;Muthiah et al, 1989;Restasari & Abdillah, 2017;Tomasz et al, 2018 (Gurkan, Deger, Zekeriya, & Teoman, 2014;Li et al, 2014).…”

Pengembangan pengetahuan terhadap sifat rheologikal isian cair dari propelan berguna untuk mendapatkan sifat slurry yang optimum. Pengembangan ini dapat dimulai dari campuran HTPB-DOA sehingga penelitian ini bertujuan untuk mengetahui pengaruh DOA terhadap sifat rheologikal HTPB-DOA yang meliputi sifat alir terhadap shear rate, viskositas dan viskositas saat zero shear rate. Dalam metodenya, DOA divariasi 0, 5, 10, 15 dan 20% dan dicampur dengan HTPB. Sifat rheologikal dipahami dengan mengukur viskositasnya pada kecepatan putar 0,5; 1; 1,5; 2; 2,5; 3; 4 dengan spindel tipe 2 dari viskometer Brookfield dan menganalisa grafik shear stress vs shear rate serta viskositas vs shear rate. Berdasarkan analisa tersebut, diketahui bahwa campuran HTPB-DOA bersifat shear thickening. Semakin banyak DOA yang ditambahkan, semakin rendah viskositas campuran, semakin rendah nilai viskositas pada zero shear rate dan semakin kuat sifat shear thickening dari campuran.

“…While Rm. Muthiah et al [36] reported that the most suitable plasticizers used with HTPB are DOA and IDP due to the ability International Integrated Engineering Summit 2014 to improve the processability and pot life of HTPB propellants. Works by several other researchers [3, 6, 10, and 12] used DOA as a plasticizer for composite propellants and accounts for around 1% to 5 % of the propellant weight.…”

Ammonium perchlorate (AP) based solid propellant is a modern solid rocket propellant used in various applications. The combustion characteristics of AP based composite propellants were extensively studied by many research scholars to gain higher thrust. The amount of thrust and the thrust profile, which may be obtained from a specific grain design, is mainly determined by the propellant composition and the manufacturing process that produces the solid propellant. This article is intended to review and discuss several aspects of the composition and preparation of the solid rocket propellant. The analysis covers the main ingredients of AP based propellants such as the binder, oxidizer, metal fuel, and plasticizers. The main conclusions are derived from each of its components with specific methods of good manufacturing practices. In conclusion, the AP based solid propellant, like other composite propellants is highly influenced by its composition. However, the quality of the finished grain is mainly due to the manufacturing process.

“…Both inert and energetic plasticizers have involved propellant and explosive formulations to improve process parameters, mechanical properties and insensitivity properties of them . 1,2,4‐Butanetriol trinitrate, trimethylolethane trinitrate, nitroglycerin, n ‐butyl‐2‐nitratoethyl‐nitramine, triethyleneglycol dinitrate, and bis(2,2‐dinitropropyl)acetal or formal are energetic plasticizers used in especially smokeless or reduce smoke propellant formulations to compensate energy loss due to reduction or removal of metallic fuel which is responsible for primary smoke generation.…”

Mechanical, thermal, and sensitivity properties of plastic bonded explosives (PBX) depend on the type of ingredients in their formulation. Aim of the work is to develop aluminized cast PBX formulations and process conditions by using alternative inert plasticizers to have similar or better properties than PBXN‐109 without compromising sensitivity properties. Although very small portion of total production of plasticizers is used for solid rocket propellant and explosive formulations, they play very significant role in that area. Both inert and energetic plasticizers have involved propellant and explosive formulations to improve process parameters, mechanical properties, and even insensitivity properties of them. Isodecyl pelargonate and dioctyl adipate are the most preferred inert plasticizers in polyurethane based thermoset propellant and explosive formulations. In addition to them, diisononyl adipate and diisononyl phthalate were used and screened as inert plasticizer candidates for aluminized cast PBX formulations. Mechanical, thermal, and sensitivity properties of PBX formulations were studied and compared in detail. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40907.
