NASA Goddard enhances spacecraft development utilizing augmented actuality

• Augmented actuality instruments have helped technicians enhance accuracy and save time in match checks for the Roman house telescope being assembled at NASA’s Goddard House Flight Heart in Greenbelt, Maryland.
• In a single case, processing a digital mannequin of a Roman propulsion system into an actual telescope chassis revealed that the deliberate design wouldn’t match over the present wiring. This end result helped keep away from the necessity to rebuild any parts.
• The Goddard R&D group engaged on this augmented actuality venture signifies that wider adoption sooner or later might save weeks of development time and lots of of hundreds of {dollars}.

Technicians armed with superior measuring gear, augmented actuality headsets and QR codes checked the suitability of some Roman house telescope constructions earlier than they had been constructed or transported by amenities at NASA’s Goddard House Flight Heart in Greenbelt, Maryland.

“We have been capable of place sensors, mounting interfaces, and different spacecraft {hardware} in 3D house sooner and extra precisely than earlier applied sciences,” stated NASA Goddard engineer Ron Glenn. “This may be very helpful to the associated fee and schedule of any program.”

Projecting digital fashions onto the true world permits technicians to align elements and search for potential overlap between them. The AR Head-up show additionally permits the precise location of the flight {hardware} to be decided for meeting with accuracy to inside a thousandth of an inch.

Utilizing NASA’s inside analysis and growth program, Glenn stated his group continues to search out new methods to enhance how NASA builds spacecraft utilizing augmented actuality expertise in a venture serving to to construct Roman at NASA Goddard.

Glenn stated the group achieved way more than they initially got down to show. “The unique aim of the venture was to develop improved meeting options utilizing augmented actuality and see if we might remove expensive manufacturing time,” he stated. “We discovered that the group can do extra.”

For instance, engineers used a robotic arm for exact measuring and 3D laser scanning, mapping Roman’s advanced wiring harness and quantity inside the spacecraft’s hull.

“By manipulating the digital mannequin of Roman’s drivetrain on this framework, we discovered locations the place the present wiring harness overlapped,” stated group engineer Eric Brun. “Tuning the drivetrain earlier than constructing it allowed the duty to keep away from expensive and time-consuming delays.” “.

The Romanian cost system was efficiently built-in earlier this yr.

Bron added that contemplating the time it takes to design, construct, transport, redesign and rebuild, their work saved many days of labor by many engineers and technicians.

“Now we have recognized a number of extra advantages to those mixtures of applied sciences,” stated group engineer Aaron Sanford. “Companions in different places can collaborate instantly by the technicians’ view. Utilizing QR codes to retailer metadata and transmit paperwork provides one other layer of effectivity, permitting fast entry to related data proper at your fingertips.” Creating AR methods for reverse engineering and superior applied sciences The constructions open up many potentialities comparable to coaching and documentation.”

Applied sciences enable 3D designs of elements and assemblies to be shared or delivered nearly from distant places. It additionally permits dry machining of cellular and modular constructions, in addition to serving to to seize correct measurements after elements are created to check to their designs.

Including a exact laser tracker to the combo might remove the necessity to create advanced bodily molds to make sure parts are exactly fitted in exact positions and orientations, Sanford stated. Even particulars, comparable to whether or not a technician can bodily lengthen his arm contained in the construction to show a nail or manipulate a component, could be resolved in augmented actuality earlier than development.

Throughout development, an engineer carrying the headset can check with important data, comparable to torque specs for particular person bolts, utilizing a hand gesture. In reality, an engineer can obtain this with out having to cease and discover data on one other machine or in paper paperwork.

Sooner or later, the group hopes to assist combine the varied parts, conduct inspections, and doc the ultimate development. “It is a cultural shift,” Sanford stated. “It takes time to undertake these new instruments.”

“It will assist us produce spacecraft and devices shortly, saving weeks and probably lots of of hundreds of {dollars},” Glenn stated. “This enables us to return sources to the company to develop new missions.”

This venture is a part of Goddard’s FY 2024 NASA Innovation Fund portfolio. Innovation Heart Fund inside the company Space Technology Mission Directoratestimulates and encourages creativity and innovation at NASA facilities whereas assembly the technological wants of NASA and the nation.
