Boom Supersonic XB-1 Specs. 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. Like any fledgling start-up, we must consider if the composites we’re choosing are even viable with the budget we’re working on. They expand at a rate more closely matching that of titanium, which is also a key material in XB-1. To not bog down the reader with multiple calculations, I included a simple calculator here! 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. We have made it to the end. To shorten this list, let’s go with the aerospace industry’s choices of carbon fiber reinforced composites and fiberglass composites. Blake Scholl, Founder and CEO, "estimates that flights on Overture will be available in 2030." Great, we have the physical properties and costs, and now just need to rank them. A higher tow size would have the individual threads closer together, while a lower tow size has increased spacing.

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. Stephen Holmes visits Hangar 14 to find out how designs from 50 years ago are still influencing supersonic flight today You’re stuck. A Quest to Choose the Best Composite for a Supersonic Aircraft. In addition to supplementing both options with a core, we’ve officially un-stuck ourselves from our many choices. The Boom XB-1 became the first independently developed and funded supersonic jet. Lots of metrology equipment and ultrasonic testing too – but plenty of wood jigs and modular ovens made of foam. by Chris April 18, 2020. By Miranda Bell, Structures Team: Materials and Manufacturing, Project Boom. Source | Boom Supersonic. Boom Supersonic is making the world dramatically more accessible, starting with XB-1, a supersonic demonstrator that will prove key technologies for safe, efficient and sustainable supersonic travel. 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. Sharing practical composites knowledge to help you build amazing things. XB-1 will roll out on October 7, 2020 and begin flight tests in 2021. We have enough information to pick our correct choice! A relatively high Young’s modulus would ensure the composite remains stiff, resisting bending and stretching. The direction of the weave also dictates the optimal forces each weave can take. XB-1’s supersonic paint job is more than cosmetic. 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 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. Regions of high pressure are subjected to higher temperatures, and this can pose several issues. In essence, the XB-1’s paint job is more than just maquillage. Boom Supersonic is redefining commercial flight by bringing supersonic flight back to the skies with Overture. Therefore, we’re looking for composites that satisfy a base calculated tension and compressive force of 700N from previous hand calculations for a wing spanwise stress. 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. The XB-1, also known as the Baby Boom, is the sub-scale technology demonstrator for Boom’s supersonic airliner Overture. N/A due to the lack of information pulled from technical sheets, and an assumption is made that the tensile strength is equivalent. 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. From there, each fiber has an associated weave. 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?). Written by Project Boom Editor on October 8, 2020. You can only pick two, so make your decision wisely. Technically it is a Mach 2.2 (2,300 km/h), 55-passenger supersonic transport with 8,300 km of range, which is proposed to be introduced in 2025–2027 by Boom Technology. MIAMI – BOOM Supersonic considered a variety of factors when designing and painting its XB-1 supersonic jet, from weight to color and material.. 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). Engines Today, we have vastly improved turbofan engines, which can produce enough thrust for supersonic flight while also being … 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. You are responsible for your own judgement and outcomes. However, before we do that, we need to calculate the weight each of these composites add. Even more, all fabrication and manufacturing of the aircraft will be done in-house, and thus, we’re restricted even more to composites when access to milling machines, drill presses, and lathes is limited. Boom's mission is to make the world dramatically more accessible by making supersonic travel mainstream. The Denver, CO, US-based aerospace industry startup is one of several groups pursuing … 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! XB-1 is a milestone on the way to Overture, Boom’s supersonic commercial jet. 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. As the aircraft flies, due to compressibility effects (at high speeds) and skin friction, the temperature of the skin rises. Unidirectional weaves would be best for uniaxial forces, or forces along the same axis. 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). Note how including the weights changed our ending choice. Boom Supersonic, the aerospace company building the world’s fastest airliner, today unveils its supersonic demonstrator, XB-1, history’s first independently developed supersonic jet. Hence the material choice also limits the maximum speed an aircraft can operate at. You don’t get to see inside the construction of a composites-intensive supersonic jet very often! Leaders of Boom’s Flight Test team share a tour of the avionics lab and talk the rigors of first flight preparations. What is the Boom Overture? What is the Boom Overture? Boom Technology, Inc., doing business as Boom Supersonic, is an American startup company designing a Mach 2.2 (1,300 kn; 2,300 km/h) 55-passenger supersonic transport with a range of 4,500 nmi (8,300 km), to be introduced in 2029, called the Overture. A lightweight aircraft will require less energy to get up to the required altitude. Boom says that supersonic passenger flight can be achieved with existing technology, building on recent developments such as composite fuselage … Easy peasy… well, we hope so at least. 4 min read. I would love to see this happen, I just question whether a market still exists for a supersonic aircraft. Figure 4: Decision matrix with non-weight and weighted choices. A high strength-to-weight ratio is critical to obtaining a lightweight aircraft without foregoing strength. There’s a lot of interesting one-off assembly fixturing too. Making the vision a reality. Carbon Fiber Composites. Applied Composites + Boom Supersonic. Unlike other projects to develop a new supersonic aircraft, only Boom Aerospace is focusing on large passenger numbers and not private jets. 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. Check out the Boom XB-1 section of their website. The data was formatted to show no decimals for readability, along with adding a weighted system to ensure we picked the right material for the job. Cheap, lightweight, or strong. Written by Project Boom Editor on October 8, 2020. The initial model would be the Boom Technology XB-1 "Baby Boom" Supersonic Demonstrator 1/3-size prototype. This site contains information that reflects the opinions of individual authors – mostly me, Chris. Our supersonic airliner will make the world dramatically more accessible—-at today's business-class fares. 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. But in 2003, after 27 years of trans-Atlantic flights, the aircraft was shuttered because of steep operating costs, inefficient fuel consumption and environmental concerns. Based on our chart, the fiberglass wins then is followed by the 12K triaxial carbon fiber. XB-1 is slated to fly for the first time in 2021 and will … While […] We are in on the concept and initial build of XB-1. 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. First things first, what do we need to look for in an aircraft? 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. Next, let’s move on to the costs! The outer coat offers a number of safety advantages, including physical damage protection, UV rays, and epoxy breakdown, and a visual tool for leak detection. I make no promises about its usefulness! This historic commercial airliner is designed and committed to industry-leading standards of speed, safety, and sustainability. XB-1 up-close. Overture is in its design phase with plans to finalize the configuration and begin building the first airliner while XB-1 is flying supersonic. 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. © 2020 Project Boom Inc. All rights reserved. Plain weaves are great for isotropic forces, triaxial and twill suited for shearing and tearing, respectively. According to Boom during rollout on Oct. 7, 2020, the composite-intensive Overture will be the world's fastest airliner and … Applied Composites is proud to be a key enabler for the next generation of innovative aircraft. Considerations have been made for the addition of a core, and for the next article, will be talked about in length. Boom Supersonic is building a faster future. Boom Supersonic is leveraging advanced technologies – such as CFD, composites and additive manufacturing – to create new era of supersonic commercial flight. 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. Now that we have our criteria, let’s limit the composites we need. The composites also expand and contract much less than metal under supersonic conditions, allowing Overture to fly at higher speeds. 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. 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. Training for supersonic speed. When will supersonic flights start? Weight. You’re stuck. 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. Boom Supersonic is building a faster future. Autoclaved Aerated Concrete for High Temperature Tooling? 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! Some of this stuff can be dangerous and the warning “don’t try this at home” applies. Explore Composites! Boom plans to roll out the first completed Overture aircraft in 2025, with entry into service planned for 2029. Posted in Design Journal. In addition, a core, depending on the material and the structure type (honeycomb, foam, or wood), will provide greater resistance to compression and crush. articles, videos, photos: Copyright 2020 Chris Rogers. Then results are in! Please do not copy without permission. To do this, we need to rank the fibers on a Decision, or Pugh, matrix. Boom’s mission is to make the world dramatically more accessible by making supersonic travel mainstream. It would be capable of trans-Pacific flight, LA-to-Sydney in 6.75 hours, traveling at 2,335 km/h (1,451 mph). 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. Boom is trying to bring back supersonic commercial air travel, which we otherwise haven’t seen other major aircraft manufacturers try.
