Hybrid Power Management-Based Vehicle Architecture

Hybrid Power Management (HPM) is the integration of diverse, state-of-the-art power devices in an optimal configuration for space and terrestrial applications. The basic vehicle architecture consists of a primary power source, and possibly other power sources, that provides all power to a common energy storage system that is used to power the drive motors and vehicle accessory systems.

Enhanced Fuel-Optimal Trajectory-Generation Algorithm for Planetary Pinpoint Landing

An enhanced algorithm has been developed that builds on a previous innovation of fuel-optimal powered-descent guidance (PDG) for planetary pinpoint landing. The PDG problem is to compute constrained, fuel-optimal trajectories to land a craft at a prescribed target on a planetary surface.

Spring Tire

A new tire is made from helical springs, requires no air or rubber, and consumes nearly zero energy. The spring tire provides greater traction in sandy and/or rocky soil, can operate in microgravity and under harsh conditions, and is non-pneumatic.

LED Lighting for Maintenance and Construction Vehicles

Strobe or rotating beacon-type emergency lighting is a requirement on all Minnesota Department of Transportation (Mn/DOT) maintenance and construction vehicles. There is an effort to replace the standard warning lighting with LED-based lights in order to reduce cost of replacement and maintenance.

Fuel-Cell Water Separator

NASA Glenn Research Center has designed, built, and tested an innovative fuel-cell water separator that not only removes liquid water from a fuel cell’s exhaust ports, but does so with no moving parts or other power-consuming components. The separator employs the potential and kinetic energies already present in the moving exhaust flow.

Fuel-Cell-Powered Vehicle With Hybrid Power Management

NASA Glenn Research Center has developed a hybrid electric utility vehicle that is powered by hydrogen-burning PEM fuel cells operating with a metal hydride hydrogen-storage unit. This vehicle utilizes ultracapacitors - rather than batteries - for storing electric energy.
