Among the epoxies we are considering using, the lowest Tg is 120०C, clearly well above the temperatures expected for both phase 1 and phase 2. Posted in Design Journal. Boom Technology has a vision: make commercial supersonic flight available to everyone, at a reasonable cost. Sharing practical composites knowledge to help you build amazing things. Unidirectional weaves would be best for uniaxial forces, or forces along the same axis. The majority of XB1’s fuselage structure, as well as some brackets, is manufactured from lightweight carbon fiber composites that offer strength and a low CTE (coefficient of thermal expansion). Making the vision a reality. Applied Composites + Boom Supersonic. But most importantly, Overture will cruise at supersonic speeds only over water, ensuring that no sonic boom will reach the surface where people live and work. MIAMI – BOOM Supersonic considered a variety of factors when designing and painting its XB-1 supersonic jet, from weight to color and material.. You are responsible for your own judgement and outcomes. I would love to see this happen, I just question whether a market still exists for a supersonic aircraft. Written by Project Boom Editor on October 8, 2020. XB-1 is the world’s first independently developed supersonic jet and, according to Boom Supersonic, will demonstrate key technologies for Overture, Boom’s commercial airliner, such as carbon fiber composite construction, computer-optimized high-efficiency aerodynamics and an efficient supersonic propulsion system. Applied Composites is proud to be a key enabler for the next generation of innovative aircraft. It would be capable of trans-Pacific flight, LA-to-Sydney in 6.75 hours, traveling at 2,335 km/h (1,451 mph). Boom Supersonic is building a demonstrator aircraft for their planned supersonic passenger jet – and they’re posting lots of interesting information, video and pictures of the process. To not bog down the reader with multiple calculations, I included a simple calculator here! Given we’re a developing team, the fiberglass option would allow us to create our prototype aircraft and test flight capabilities before moving on to the more expensive, but lightweight option of the 12K triaxial weave carbon fiber. However, the engines for Overture have not been selected. Boom Supersonic is building a faster future. Blake Scholl, Founder and CEO, "estimates that flights on Overture will be available in 2030." The materials and technology are coming together in a way that’s innovating the industry. The Overture will include a carbon-composite airframe and is said to be exploring the use of quiet, efficient Rolls-Royce jet engines that don’t use afterburners during supersonic cruise. This site contains information that reflects the opinions of individual authors – mostly me, Chris. XB-1 is the demonstrator airplane for Overture and a critical step toward mainstream supersonic travel. XB-1 is slated to fly for the first time in 2021 and will … XB-1 is powered by three General Electric J85-15 engines, adapted by Boom for Mach-2.2 operation. We take our criteria, normalize the data, add a weighting system based on importance, and rank the fibers on a scale from 1 to 5, with 5 being the best and 1 being the worst, then multiply the 1 to 5 number by the weight to create the ending values. To design and build XB-1, Boom recruited a team of experts from around the industry, forged relationships with key suppliers, and built a strong safety culture. Our supersonic airliner will make the world dramatically more accessible—-at today's business-class fares. In addition to supplementing both options with a core, we’ve officially un-stuck ourselves from our many choices. Check out the Boom XB-1 section of their website. The XB-1, also known as the Baby Boom, is the sub-scale technology demonstrator for Boom’s supersonic airliner Overture. Given we’re running (well, flying) at high speeds, there are varying loading conditions acting on all regions of the aircraft; such as shear, compressive, and tensile forces. Given our speeds, we don’t have a high enough temperature to warrant a high weight percentage, and this applies to the rest of the physical properties. Figure 3: Costs of each composite with an exception made for HDPE due to being sold in sheets. The decision can’t be taken lightly; one wrong move and you’re the reason why 60% of the budget went into materials, or you’re the reason why the team has to make a new aircraft every year. XB-1’s supersonic paint job is more than cosmetic. The company acknowledges XB-1 as the end product of years of … You’re stuck. Stephen Holmes visits Hangar 14 to find out how designs from 50 years ago are still influencing supersonic flight today The company is currently building the XB-1, a flying one-third-scale demonstrator dubbed “Baby Boom,” to demonstrate the key technologies of its coming full-scale, faster-than-sound Boom aircraft. Sonic boom represents an additional noise source that we, as a supersonic manufacturer, have to address — and thanks to modern aerospace composites, we have more freedom in shaping the aircraft optimally for sonic-boom reduction. This is why the speed of the Concorde was limited to Mach 2. Boom Supersonic - 12876 E Adam Aircraft Cir,, Englewood, CO 80112 - Rated 4.9 based on 19 Reviews "Boom = Innovation. LinkedIn co-founder and early Boom investor, Reid Hoffman, and former CTO of Lockheed Martin and Boom advisor, Dr. Ray O. Johnson highlight the importance of XB-1 for the future of travel. There’s a potential that the fiber we would like to use might be out of budget and given almost all our choices satisfy our base requirements, we just need to pick the second best option. The Boom Overture is a new aircraft concept under development to bring back supersonic travel to the regular aircraft flyer. Then results are in! Boom Supersonic is leveraging advanced technologies – such as CFD, composites and additive manufacturing – to create new era of supersonic commercial flight.

Boom will roll out the first completed Overture aircraft in 2025, with entry into service planned for 2029. (CNN) — Over 50 years after Concorde first took to the skies, a brand new supersonic jet is preparing for lift off. Boom Supersonic’s XB-1 is a one-third-scale demonstrator for the Overture, a follow-on 75-seat airliner it aims to introduce into commercial service later this decade. articles, videos, photos: Copyright 2020 Chris Rogers. Like any fledgling start-up, we must consider if the composites we’re choosing are even viable with the budget we’re working on. Each fiber has a tow size (the number followed by a K), which represents the number of individual carbon filaments in the tow – i.e. The Concorde, the first supersonic aircraft offering passenger service, transported people from the eastern seaboard of the U.S. to Paris and London in half the time of standard commercial airlines. As the aircraft flies, due to compressibility effects (at high speeds) and skin friction, the temperature of the skin rises. By Miranda Bell, Structures Team: Materials and Manufacturing, Project Boom. However, before we do that, we need to calculate the weight each of these composites add. Cheap, lightweight, or strong. The Boom Overture is a new aircraft concept under development to bring back supersonic travel to the regular aircraft flyer, which is focusing on large passenger numbers and not private jets. It will be fun so watch them finish the build and move on to testing and flying! Figure 2: Physical properties of various industry standard composites. Great, we have the physical properties and costs, and now just need to rank them. Unidirectional means the fibers are all woven in one direction, while plain, twill, and triaxial dictate varying angles and spacing when woven together. If you see any mistakes or disagree with anything here I would love to have a chance to learn from you – please let me know! So, just how do we figure out the best material for our aircraft? XB-1 is a milestone on the way to Overture, Boom’s supersonic commercial jet. This historic commercial airliner is designed and committed to industry-leading standards of speed, safety, and sustainability. Explore Composites! As part of the Project Boom’s Structures team, specifically the Materials and Manufacturing subteam, it is our responsibility to figure out the proper criteria for a supersonic aircraft to be successful at hitting supersonic speeds, safely and non-destructively. The year started well for Boom Supersonic, a Colorado-based firm that has been building its Overture supersonic airliner since 2014. Leaders of Boom’s Flight Test team share a tour of the avionics lab and talk the rigors of first flight preparations. The Denver, CO, US-based aerospace industry startup is one of several groups pursuing … by Chris April 18, 2020. Boom says that supersonic passenger flight can be achieved with existing technology, building on recent developments such as composite fuselage … Based on our chart, the fiberglass wins then is followed by the 12K triaxial carbon fiber. Boom is trying to bring back supersonic commercial air travel, which we otherwise haven’t seen other major aircraft manufacturers try. N/A due to the lack of information pulled from technical sheets, and an assumption is made that the tensile strength is equivalent. 4 min read. A higher tow size would have the individual threads closer together, while a lower tow size has increased spacing. An example using 1K plain weave carbon fiber and a core of HDPE is loaded in with inputs on the left and the outputs on the right side of the calculator. Boom is building a supersonic airliner capable of carrying 55 premium passengers at Mach 2.2 (2,335 km/hour or 1,451 miles/hour), more than twice as fast as current passenger airplanes at the same cost as today’s business class fares. Our supersonic airliner will make the world dramatically more accessible—-at today's business-class fares. Associate Editor, CompositesWorld. There’s a lot of interesting one-off assembly fixturing too. “Boom has come a long way. Boom Supersonic XB-1 Build. In essence, the XB-1’s paint job is more than just maquillage. In addition, a core, depending on the material and the structure type (honeycomb, foam, or wood), will provide greater resistance to compression and crush. A Quest to Choose the Best Composite for a Supersonic Aircraft. I make no promises about its usefulness! A way to estimate the temperatures that can be reached is to look at the stagnation temperature of the air, which in simple terms converts the kinetic energy of the air into equivalent heat (supported by the reversibility principle of motion). To further reduce the weight and cost of the material, a core material can be added that separates the fibers into regions of highest stress, increasing the bending stiffness of the part. Please do not copy without permission. We have enough information to pick our correct choice! We can’t decide to choose the luxury options and not have a way to pay for them. In comparison, cost and weight are the most important criteria for us. 12K = 12000 filaments per tow. From what I can see it looks like a slightly fussier version of the race-boat building world that I am familiar with – lots of manual laminating, fitting, prepping and bonding! Posted in Design Journal. Written by Project Boom Editor on October 8, 2020. To shorten this list, let’s go with the aerospace industry’s choices of carbon fiber reinforced composites and fiberglass composites. Boom's mission is to make the world dramatically more accessible by making supersonic travel mainstream. You don’t get to see inside the construction of a composites-intensive supersonic jet very often! Metals lose their strength at higher temperatures as diffusion starts to occur and dislocations are able to move more freely. Hours spent researching the best material, and you’re stuck on the options that either hurt your wallet to even look at the numbers, or turn your aircraft into a flying brick with the mass of an elephant. We have made it to the end. Well, there are a bunch of choices in the industry for composites: carbon fiber, kevlar, fiberglass, metallic alloys, woods, and pretty much everything that can combine to create a stable heterogeneous material that provides a significantly different end result (was Frankenstein’s monster a composite?). Collins Aerospace Systems (Cedar Rapids, Iowa, U.S.) a unit of Raytheon Technologies (RTX), has signed a collaboration agreement with Boom Supersonic (Denver, Colo., U.S.), to advance nacelle technology on Boom's forthcoming flagship supersonic airliner, Overture. Be safe! Lots of metrology equipment and ultrasonic testing too – but plenty of wood jigs and modular ovens made of foam. Our decision is no longer plagued by 20 different choices, but now we’re stuck with 2 close scores and that’s not a bad thing. Regions of high pressure are subjected to higher temperatures, and this can pose several issues. Figure 4: Decision matrix with non-weight and weighted choices. A lightweight aircraft will require less energy to get up to the required altitude. Engines Today, we have vastly improved turbofan engines, which can produce enough thrust for supersonic flight while also being … Overture is in its design phase with plans to finalize the configuration and begin building the first airliner while the demonstrator aircraft XB-1 is flying supersonic.
