Abstract: A combustion system for a vehicle having an engine includes a hydrogen fuel system having a fuel source providing a hydrogen fuel, a combustor operable to combust the hydrogen fuel to generate combustion gases, and a fuel delivery assembly operable to deliver the hydrogen fuel from the fuel source to the combustor. A first control system has a first update rate and is operable to control one or more operational aspects of the turbine engine. A second control system is in communication with the first control system and the hydrogen fuel system and has a second update rate faster than the first update rate. The second control system is operable to monitor at least one parameter associated with the hydrogen fuel system and output at least one control signal to the hydrogen fuel system to control the delivery or the combustion of the hydrogen fuel.

Abstract: A latch assembly and telescoping mast having a plurality of telescoping tube sections including the same wherein the latch assembly includes a first latch member mounted to an associated first tube section, a second latch member mounted to an associated second tube section and configured to selectively engage the first latch member to interlock the first and second associated tubes when the associated first tube section is at least partially extended from the associated second tube section, and a trigger member mounted to an associated third tube section. The second latch member includes a latch housing having an opening configured to receive the trigger post when the second associated tube section is retracted into the third associated tube section.
