A 1000-ft aeroballistics range was used to obtain free-flight stability and drag data for slightly blunted 10-deg semiangle cones with and without ablation occurring on the conical skirts. The configurations investigated included ones having fore- and aft-positioned ablation sleeves, as well as one with a skirt material which did not ablate. The investigation was conducted for a Mach number near 14 and a Reynolds number, based on cone length and free-stream conditions, of about 55000.
