A toy projectile comprising an upper stage having a segmented, tubular rocket-simulating body in which segments or vanes are hinged and formed to provide a rocket vehicle-like configuration in the closed condition and, upon opening, provide radially disposed air foil members which operate in the manner of an autogyro or helicopter to provide gyro rotation of the vehicle for slow descent after it has reached its apogee. The lower stage comprises a tube which is slidably and frictionally receivable within a lower adaptor portion on the upper stage so as to removably mount the lower stage on the upper stage. A solid grain propellant engine, including a thrust charge, delay and separation charge, is mounted in the tube of the lower stage. The lower stage serves to retain the segments or vanes in a closed condition before separation of the upper and lower stages by the separation charge within the lower stage.

A toy projectile having an upper stage and a lower stage, said upper stage comprising a plurality of vanes movably mounted thereon for movement between a closed, substantially longitudinally extending position and an open, substantially radially outwardly extending position, means for biasing said vanes to said open position, and an adaptor portion disposed on the lower end of said upper stage and comprising a downwardly opening tubular section; and said lower stage comprising a first tubular portion having an upper end adapted to be received within said tubular section of said adaptor portion to removably secure said lower stage to said upper stage, means mounted on said first tubular portion for engaging the lower portions of said vanes to retain them in said closed position when said upper and lower stages are removably connected, and means mounted in the lower end of said first tubular portion for propelling said projectile and for separating said upper and lower stages to enable the lower portions of said vanes to move away from said retaining means, whereby said biasing means moves said vanes to said open position.
