Pace Levy - Aerospace

Aerospace Pace Levy is well suited to provide advanced imaging system support for unique or proprietary testing environments. Our staff has delivered superior performance to researchers who count on us to provide that "one shot, million dollar image."
	Mars Lander Airbag System The airbag system for the Lander was critical to success of the mission and a tremendous amount of testing and analysis went into the final design. Much of that testing was done at the NASA Plumbrook facility in Sandusky Ohio, were NASA has two huge vacuum chambers. One chamber is capable of maintaining a temperature of -320F and this is where the airbag inflation system was tested. The other vacuum is the largest in the world (seen at left) measuring 100-ft in diameter by 122-ft high. This photo shows the airbag system inflated setting above an inverted platform. To test the airbags ability to withstand an impact on rocks that may be encountered on the Mars surface, simulated rocks were placed on the platform and the airbag system drop on them. High speed imaging allowed researchers to analyze the exact point of impact and determine various characteristics with rips, tears and airbag failures.
	Delta IV Shroud Separation This rocket placed in the vacuum chamber (SPF) at the NASA Plumbrook facility in Sandusky Ohio was tested to ensure the shroud would separate from the satellite platform without damaging the satellite itself. High speed imaging was a critical component of the testing to visualize the separation at the moment the two halves of the shroud were blown apart. Several high speed cameras were place in environmental enclosures at strategic locations around the shroud. Distance and time resolution calibrations were conducted to precise measure displacement as a function of time in the post-processing phase of the experiment. The shroud at left is being held up by an array of ropes designed to catch the shroud halves before they impact the floor. Our personnel were involved in test this and other shroud configures over several years.
	Titan V Shroud This image of the Titan V shroud was taken at the NASA Plumbrook facility inside the large vacuum chamber (SPF) Space Power Facility. Visible at the lower left and right are the entry doors to the chamber that measure 50 ft. by 50 ft.
