Scissoring mechanisms deploying at low speed

A system comprising:

• a motor,
• a driven blade coupled to a driven rotor rotating around a first shaft coupled to the motor,
• a following blade coupled to a following rotor rotating around a second shaft concentric with the first shaft, and
• a scissoring mechanism configured to move the following blade and the driven blade between a stowed configuration and a deployed configuration, the scissoring mechanism comprising:
• a positioning mechanism configured to keep the following blade and the driven blade in the stowed configuration, wherein disengaging the positioning mechanism moves the driven blade to a predetermined angle with respect to the following blade in the deployed configuration while the motor is operating at zero or near-zero speed;
• and
• a latch mechanism configured to keep the following blade and the driven blade in the deployed configuration, wherein engaging the latch mechanism locks the following blade at the predetermined angle with respect to the driven blade in the deployed configuration allowing the following blade and the driven blade to rotate together,
• wherein:
• the positioning mechanism includes a first arm and a second arm coupled to each other via a pair of scissoring links and a pair of springs, wherein the first arm is coupled to the second shaft and the second arm is coupled to the first shaft,
• in the stowed configuration, the pair of springs keep the pair of scissoring links in a closed configuration, wherein in the deployed configuration, the pair of springs keep the pair of scissoring links in an open and extended configuration,
• the latch mechanism includes a pawl provided on at least one of the first arm or the second arm, and a detent, and
• in the stowed configuration, a portion of the pawl is caught in the detent.
