Abstract
In this paper, preliminary design of an academic symmetric planar scramjet using analytical method is developing by undergraduate and graduate students of Universidade Federal do Rio Grande do Norte (UFRN), designed to fly at 20 km of altitude with Mach number 5.79, integrated as a payload of Brazilian rocket engine S30. It is presented the analytical formulation used to develop the model, considering air as an ideal gas, with no viscous effects. It is done a comparation between the scramjet in power-off (with no heat addition) and power-on (with heat addition) configuration, comparing the thrust generated by the hypersonic vehicle and its efficiency.
