An autonomous-rotorcraft is ideally suited for Martian exploration as well as non-vacuum planets exploration due to its unique features for soft landing when compared to the traditional surface rovers. Herein we demonstrated the capability of the in-house designed variable speed dual-head electromagnetic (DHEM) propulsion system for producing continuously the reciprocating moment of a magnetic piston using a solar powered Polarity Changer Timing Circuit (PCTC). The DHEM device can create the spinning motion to the planet Landers and further propelling the craft without any propellant systems. The spinning speed can be altered by altering the reciprocating speed of the magnetic piston by varying the pole strengths of the magnetic heads and/or the timing of the PCTC. The uniqueness of the DHEM device comes from the fact that at the propelling conditions the system can be effectively integrated with a connecting rod and a crank shaft for getting the rotary motion continuously for various systems and subsystems applications for astronomical studies lucratively. In this paper parametric analytical studies have been carried out for estimating the dropping time and further examining the performance characteristics of the lander for the desirable soft landing at various design options and operating conditions. The proposed multipurpose DHEM device merits further design optimization for shaping deep space exploration probes and planet landers. The methodology presented herein is a pointer towards for the design optimization of planet landers for various aerospace applications.
