Concurrent rocket engine pre-conditioning and tank filling is disclosed. A disclosed example apparatus includes an inlet valve to supply a rocket propellant tank that is associated with a rocket engine with rocket propellant, and a flow director to direct at least a portion of a flow of the rocket propellant from the inlet valve to a chill line of the rocket engine to thermally condition the rocket engine as the rocket propellant tank is being filled with the rocket propellant.

Guide vane check valve assemblies and poppets for guide vane check valve assemblies are disclosed. A guide vane poppet includes an elongate central core configured to form a fluid seal with a valve body of the check valve assembly. The guide vane poppet additionally includes an elongate outer skirt and at least one guide vane radially extending between the elongate central core and the elongate outer skirt. A check valve assembly includes a valve body with a central cavity, an inlet to the central cavity, an outlet from the central cavity, and a spring seat, and further includes a spring and a poppet. The spring is oriented to press against the poppet and to urge a poppet-side sealing surface of the poppet into sealing engagement with a body-side sealing surface of the valve body.

A system and method for collecting test data from a unit under test (UUT) in a multi-gravity environment is disclosed. In one embodiment, the method comprises determining a desired accelerative load profile for the UUT, determining the commanded flight profile of a flight vehicle at least in part from the desired accelerative load profile and a predicted dynamic response of the flight vehicle having the UUT mounted thereto to the commanded flight profile, commanding the flight vehicle having the UUT mounted thereto to fly the determined flight profile, and collecting the test data using a data acquisition system communicatively coupled to the UUT.
