Parachute Dynamics Investigations Using a Sensor Package Airdropped from a Small-scale Airplane
نویسندگان
چکیده
We explore the utility of various sensors by recovering parachute-probe dynamics information from a package released from a small-scale, remotecontrolled airplane. The airdrops aid in the development of datasets for the exploration of planetary probe trajectory recovery algorithms, supplementing data collected from instrumented, full-scale tests and computer models.

A Miniature Parachute-probe Dynamics Test-bed
Small-scale sensor packages and parachutes manufactured for model rocket recovery were handdropped from within a building in order to gain familiarity with the descent kinematics of a planetary probe through an atmosphere. A number of parachute-probe systems ranging in size, shape, weight, riser length, and sensors were dropped while exterior video cameras and onboard sensor data were collected...
متن کاملInfluences of Small-Scale Effect and Boundary Conditions on the Free Vibration of Nano-Plates: A Molecular Dynamics Simulation
This paper addresses the influence of boundary conditions and small-scale effect on the free vibration of nano-plates using molecular dynamics (MD) and nonlocal elasticity theory. Based on the MD simulations, Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is used to obtain fundamental frequencies of single layered graphene sheets (SLGSs) which modeled in this paper as the mo...

airplane in presence of asymmetric left-wing damaged. Variations of the aerodynamic parameters, mass and moments of inertia, and the center of gravity due to damage are all considered in the nonlinear mathematical modeling. The proposed discrete-time nonlinear MRAC algorithm applies the recursive least square (RLS) algorithm as a parameter estimator as well as the error between the real ...

39 The development of computational models that predict the aerodynamic performance of parachute systems has significantly enhanced the technology of airdrop systems by providing alternatives to or complementing drop tests and laboratory experiments. Increases in the scope and reliability of computational modeling are bringing current technology closer to establishing “virtual proving ground” m...
متن کاملMulti-scale analysis of polysilicon MEMS sensors subject to accidental drops: Effect of packaging
The effect of packaging on the impact-carrying capacity of micro electro-mechanical systems (MEMS) is investigated, with specific reference to a translational accelerometer. By exploiting the small ratio between the masses of MEMS and package/die (typically 10 3 or less) a decoupled two-scale, finite element approach is adopted: at the package/die length-scale the dynamics of whole device after...
