Trajectory estimation for a hybrid rocket
نویسندگان
چکیده
This paper presents a research work to develop a navigation technique for a class of nano-micro space rocket. Onboard MEMS inertial sensors are used in view of post-flight trajectory estimation. Combined with synchronized measurements of the combustion engine which is of hybrid type and uses N2O and PE, we show how the relative redundancy of the data can be used to calibrate a thrust model. Experimental results are presented and stress the numerous difficulties needed to be resolved. Quantitative results are provided along with estimates of the obtained accuracy.

متن کاملModelling the dispersion of aircraft trajectories using Gaussian processes
This work investigates the application of Gaussian processes to capturing the probability distribution of a set of aircraft trajectories from historical measurement data. To achieve this, all data are assumed to be generated from a probabilistic model that takes the shape of a Gaussian process. The approach to Gaussian process modelling used here is based on a linear expansion of trajectory dat...
متن کاملTrajectory Prediction for a Typical Fin Stabilized Artillery Rocket
Abstract: This paper investigates the trajectory prediction and dispersion for unguided fin stabilized artillery rocket in order to explain the importance of the rocket production accuracy and the benefit of using guided rockets. The total dispersion results mainly from three effects. The first is the dispersion due to rocket production inaccuracy, which includes propellant mass, composition in...
