Komposisi laker dan bahan api yang digunakan dalam fabrikasi propelan pepejal mempengaruhi kadar pembakaran. Kajian ini melihat pengaruh mengubah peratusan komposisi kedua-dua bahan tadi. Hasil ujikaji yang diperolehi, menunjukkan bahawa kadar pembakaran berkurangan dengan pertambahan peratusan laker apabila bahan api dimalarkan pada 29%. Bagaimanapun, apabila laker ditetapkan kepada 22% dan komposisi bahan api diubah-ubah, kadar pembakaran menunjukkan plot parabola dengan komposisi optimum bahan api pada 28.6%.Kata kunci: Kalium nitrat; sulfur; aluminium; kadar pembakaran; roket pepejalThe composition of lacquer and fuel used during fabrication of solid propellant affects the burning rates. This study shows the effect of varying the percentage composition of both items. Results obtained show that the burning rates reduce with increase in laker percentage when fuel was set constant at 29%. However; when lacquer was set constant at 22% and at varied fuel compositions, the burning rates show a parabolic plot with the optimum composition at 28.6% fuel.Key words: Kalium nitrate; sulfur; aluminium; burning rate; solid rocket
