Abstract
Methods and apparatus are disclosed for the controllable deployment of a samara wing from a spinning housing by use of an active deployment system. The active deployment system operates to deploy the samara wing as a function of time, for example a step function, or a monotonic function. The samara wing may be attached to a base, which may include a releasable portion. The active deployment system may include an electronic control unit and release means. Suitable release means include, but are not limited to pin actuators, explosively actuated cutters, and the like. Suitable electronic control units include programmable electronic sequencers and the like.
