Appl. No.:

17/196102

Inventors:

- Cambridge MA, US
Mark Silver - Bedford MA, US

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

B64C 27/33

Abstract:

An aerial vehicle with a plurality of selectively collapsible arms capable of transitioning between an extended state and a contracted state is described. In the extended position, the distance between the main body of the vehicle and the rotor associated with each arm is maximized. In the contracted state, the distance between the main body of the vehicle and the rotor associated with each arm is minimized. In certain embodiments, each of the arms may include one or more tape springs that are biased to selectively move the associated one or more rotors of each arm between the retracted and extended states.

Abstract:

An imaging system includes a metering structure and a plurality of foldable members disposed around a periphery of the metering structure. Each foldable member in the plurality of foldable members includes an arm comprising a strain deployable composite and a reflector disposed on the arm. The arm in a respective foldable member in the plurality of foldable members is configured to hold the respective foldable member toward the metering structure in a first state and to hold the respective foldable member away from the metering structure in a second state such that the reflector of the respective foldable member forms part of a sparse aperture in the second state.

Abstract:

The present invention generally relates to an electromagnetic field vector sensing receive antenna array system for installation and deployment on a structure. A multipolarized array of collocated antenna elements is used to provide calibrated amplitude and phase radiation patterns with monopole, dipole, and loop modes generated from crossed loops connected to a beamformer. The invention has applications for installation and deployment on a tower, balloon, satellite for radio frequency sensing and location of low-frequency galactic emissions. The novel receive antenna array system comprises a multipolarized vector sensor antenna array. The disclosed direction-finding vector sensor can be installed and deployed on a structure and can detect and locate radio frequency emissions from galactic sources. The key system components of the receive antenna array system consist of deployable antennas, receivers, signal processing computer, and communications link.
