Ammonium perchlorate composite propellant (APCP) is a modern fuel used in solid-propellant rocket vehicles. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by the nature of how it is processed. APCP is cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing regularity and repeatability, which are necessary requirements for use in the aerospace industry.

  • On appelle propergol composite à perchlorate d'ammonium, ou PCPA, un matériau constitué d'une matrice macromoléculaire en polymère combustible comme liant, chargée de perchlorate d'ammonium NH4ClO4 comme oxydant, et d'aluminium pulvérulent comme combustible. Le polymère est généralement à base de polybutadiène hydroxytéléchélique (PBHT), mais peut également être constitué de terpolymère polybutadiène – acide acrylique – acrylonitrile (PBAN). (fr)
  • Propelan Komposit Amonium Perklorat (APCP) adalah propelan roket padat modern yang digunakan dalam kedua kendaraan roket berawak dan tak berawak. Ini berbeda dari banyak propelan roket padat tradisional seperti bubuk hitam atau seng-sulfur, tidak hanya dalam komposisi kimia dan kinerja secara keseluruhan, tetapi juga oleh sifat bagaimana diproses. APCP dilemparkan ke dalam bentuk, sebagai lawan bubuk menekan seperti bubuk hitam. Hal ini memungkinkan untuk keteraturan manufaktur dan pengulangan, yang merupakan persyaratan yang diperlukan untuk digunakan dalam industri aerospace. (in)
  • コンポジット推進薬(コンポジットすいしんやく、英: Composite Propellant)は、燃料と酸化剤が混合後も不均質になっている不均質系推進薬のうち、酸素を含んだ微粒子と炭化水素系ポリマーからなる推進薬である。 代表的なものとして酸化剤には過塩素酸アンモニウム、燃料にはHTPB(末端水酸基ポリブタジエン)がある。過塩素酸アンモニウムは燃焼時に大量の塩化水素が生じるなど発射後に毒性が強いガスが多量に拡散する問題を抱えており、代替品の開発が急がれている。 (ja)
