The potassium nitrate (KNO<inf>3</inf>)/sucrose (C<inf>12</inf>H<inf>22</inf>O<inf>11</inf>) propellant, known as KNSu, is traditionally used in rocket studies by amateur groups. Performance tests of KNSu, whose composition is 65 wt% KNO<inf>3</inf> and 35 wt% C<inf>12</inf>H<inf>22</inf>O<inf>11</inf>, cold-manufactured by mechanical press, are presented in this paper. The study determines the behaviour of density (ρ) and burning rate (r) as function of compression pressure (P<inf>c</inf>) for the propellant grain manufacturing. Forty-four samples were prepared and tested, for seven different values of P<inf>c</inf>. It was observed that ρ and r depend on P<inf>c</inf>, according to quadratic polynomial functions, and the mass flux per unit area is a constant.
