Abstract

Augmented reality applications annotate real world withCG. They make the environment around interactive by addingdigital 3D models or any other information over and aroundthe objects in its radius in real-world. In the case of aerospaceengineering, AR is a next-gen of designing and engineeringcomponents and structure for aircraft and spacecraft.

Key Words:Augmented Reality(AR); overlaying; next-gen.

1 Introduction

Augmented reality is key, futuristic technology through which ausers vision is enhanced and made smarter by overlaying CG in

real time. In marker based AR, the contextual digital informa-tion and CG tied together with the vision. Augmented reality isan emerging and essential technology and has found applicationsin various fields such as medical, defence, composite engineering,engineering and simulation of aerospace structure, such as rocketmotors, an airplanes wing and etc.

2 PREVIOUS WORKS IN THE FIELD

A. Boeings DevelopmentsBoeing is known to be the worlds largest aerospace company

and one of the leading manufacturer of commercial airliners anddefence, security, space systems. As theyre the leading exporter,the company supports airlines and allied government customersin 150 countries and has a record of leadership and innovationin aerospace. The Company employs more than 1,65,000 peopleacross the U.S. and other 65 countries., with corporate offices inChicago. Boeing has a history of Augmented Reality glasses fromas early as 1995, when Boeing started experimented with heads-updisplays and primary software. Due to the constrains of early tech-nologies, the technology wasnt a viable strategy. As of with todaystechnologies, the lower costs and significant increase in computingpower, Boeing was able to develop a cordless head-mount able dis-play like the Google Glass. The team named the software projectJuggernaut, but the prototypes wasn’t able to pull information fromBoeing’s databases in real time.

To develop an enterprise-grade app for Google Glass, Boeingput a proposal and caught the interest of APX Labs, the developerof a smart glass software platform called Skylight as a team, theyproduced an enterprise-grade glass app which Boeing could handout to its technicians on the assembly line. The app works byallowing a user to scan for a QR code, which activates the wirelesssoftware, and then scan another code to load the instruction. Theapp supports Glass voice commands, and also lets users streamwhat they’re seeing to another technician in the event of somethingunexpected. The software was used only by a small number ofBoeing Technicians, as a part of a pilot program that was closed.But the company was interested in making app of same genre forthe assembly line, even possibly the International Space Centre.

Airbuss DevelopmentsAirbus is aerospace manufacturer with facilities mainly in Ger-

many, France, Spain, the UK, with global diversity, consisting ofmore than 58,000 employees, the companys manufacturing oper-ations set an industry benchmark for both efficient and quality.Another enterprise-grade AR solution that is already being in usecomes from Airbus, with new aircrafts production process is com-pletely being developed with digital tools, Airbus collaborated with

other companies to create the MiRA(Mixed Reality Application) in2009.

This newly developed app increases productivity in productionfacilities by using Augmented Reality to scan components and de-tect errors. In the production the Airbus A380, MiRA, which atpresent conics of a tablet computer and a specially developed arrayof sensors and software, helped reduce the time need to check tensof thousands of brackets in the airplane structure from 300 hours toastonishing 60 hrs. Late discoveries of damaged, wrongly position,or brackets which have been missed reduced by 40 %

3 OUR APPLICATION

With all the current progress and current technologies taken intoaccount, we took the worlds best mobile operating system, ApplesiOS as our platform to build our AR app for use in such industries asit has rich and capable software and mobile hardware technologies,consumer grade hardware such as iPads and iPhones will be suffi-cient to execute our AR app to design, build, and analyze aircraftor spacecraft components and structures. The app is designed in away that, it can be used in anyplace that has adequate lighting, freespace to move around and explore the structure, The figure, showsthe screenshot of a pre-release alpha version of our app running onan iPhone.

The App clearly demonstrates how a virtual 3D object, in this casean Airbus A350-1000 XWB is placed on a surface and ready to beexplored and examined by an engineer. This gives the companiesa huge flexibility, both in terms of cost reduction by using con-sumer grade devices and availability of the devices. These iPhonesand iPads use highly accurate IMU (Inertial Measurement Unit,combined with its processing power and highly capable softwaretechnologies such as ARKit, its no wonder that not only AR isthe future of R&D, but also its becoming more affordable for themasses. Our App would be the one of the first iteration of AR forAerospace manufacturing.

With Apples powerful tools, it has become more intuitive tocreate and deploy these useful apps with minimum effort. Thefigure below shows how to components are put together in the IDEto be built.

The use of AR is not only limited for the purpose of engineeringand designing, but also has a huge potential for testing componentsand structures.

4 MATHEMATICS INVOLVED IN AR

The devices sensor array supplies the device’s location and withalready available coordinates of the location we want to look at. Atfirst the difference in the latitude and longitude values of the twopoints. These different measurement mean that we can construct aright-angled triangle and calculate at what angle from our currentposition & another position is given. At this point we can then readthe value from the compass from the phone and determine azimuthangle of our device is pointing at. The readings from the compass

will denote the angle directly in the centre of the cameras view,the software then calculates the full range of angles currently dis-

5 PROCESSING THE DATA:

The data as retrieved and sent to the corresponding APIs to handleand compute and display the corresponding output, in our case, the3D object is placed in relation to the real world.

6 CONCLUSION:

The research comes to a conclusion that, with the help of our Appli-cation, the use of AR will reach out even more people than ever be-fore by using consumer grade level hardware to execute enterprise-grade software, as these devices are highly capable of doing so whichalso leads to decrease in cost.
