2D flowfield of truncated linear aerospike nozzle is investigated. Numerical simulations carried out both without and with differential throttling for thrust vectoring. Results compare well with experimental data. In differential throttling mode, relationship between flow structures and resultant side-force is investigated. Effect of differential throttling on thrust and thrust-angle is analyzed.
