Telah dilakukan analisis hasil penelitian propelan dengan variabel kandungan aluminium terhadap hasil energi pembakaran. Pengukuran besarnya energi pembakaran propelan dilakukan dengan bomb calorimeter. Sampel propelan dibuat dengan mencampur HTPB dan aluminium selama 15 emnit dilanjutkan pencampuran dengan AP halus selama 20 menit, lalu dengan AP kasar selama 50 mrnit. Setelah pengadukan berakhir maka ditambahkan TDI dan diaduk selama 15 menit. Kandungan Al di variasi dari 8% hingga 18%. Energi pembakaran yang dihasilkan adalah 2885 kal/gr hingga 3750 kal/gr. Pada 18% Al energi pembakaran mulai menurun. Penurunan ini diakibatkan oleh sebagian besar sampel yang terbakar sama dengan sampel yang mengalami erosiv.
