Full textThis report of a conceptual design of an electric driven aircraft was driven with the goal of making the flying sector more environmentally viable. The designated mission was chosen freely for the airplane. The result became a short distance plane with a range of 500 km, seating for eight passengers, primarily aimed towards companies. It was decided that the plane would have its cruising altitude at 4500 m, with a cruising speed of 280 km/h and have a short takeoff and landing distance. The airplane would be able to climb with a vertical speed of 6.67 m/s and have a stall speed of 150 km/h. From the specifications and the assumptions regarding different variables, the fuel weight and total weight was decided to be 2654 kg and 8294 kg respectively. The range of a corresponding aircraft driven with fossil fuels were calculated to be 2070 km. A constraint diagram was then constructed based on five chosen requirements. From this diagram the least power to weight and the highest possible wingloading was determined. A point slightly higher than the least required power to weight was chosen, leading to the engines needing to produce 1900 hp at takeoff. The wing area could be calculated from the decided wingloading and it ended up at 44 m^2 with a wingspan of 23.8 m because of a previously chosen aspect ratio. The length of the fuselage was calculated to be 16.2 m and its effective diameter 2.03 m. Finally an initial layout could be developed where a relationship between the wing and horizontal stabilizer was calculated and the center of gravity for the airplane was placed. The final airplane has a longer wingspan, is heavier and has a shorter range than what similar aircraft that are not driven with electricity have. It can be seen that the cruise speed can be increased above the 280 km/h in the constraint diagram, but the specified requirements were met, which was the main priority.

Full textDuring the spring semester 2019 the students partaking in the aerospace bachelor thesis were tasked to design an electric airplane to study the plausibility of an electric future for the aviation industry. It comes as no surprise that commercial aviation is a big polluter and electric powertrains could help drive it towards a sustainable future. The airplane developed in this report is an electric airplane in the light business jet class. Due to the required development of completely new technologies and the fact that the aircraft would be manufactured in small quantities the initial price of the craft would be rather high. This ties in nicely with the target audience of politicians and executives as they tend to be more capable of purchasing these products. With a carrying capacity of 8 passengers, corresponding to a payload up to 960 kg (including luggage) and a maximum range of 1500 km, the airplane is perfect for flights to cities on the continent. For example a flight from Stockholm Arlanda to Berlin Tegel (830 km) or Arlanda to Wien Flughafen (1240 km). By examining historical data on planes in the same class the maximum take-off weight was estimated to 11000 kg. This value was later used to construct the constraint diagram. By considering the usage of the plane specific constraints were set. These constraints were a function of wing loading and by plotting them together in a diagram an optimal point could be found. This point was 250 kg/m^2 which meant a power rating of 1580 BHP and a wing area of 43.8 square meters. With the maximum take-off weight set an estimation of the fuselage length could be done by comparing it with historical data on similar planes. The fuselage length was estimated to be 16,1 m. The wing was placed on top of the fuselage in a high wing configuration. To complete the 1500 km journey the aircraft needs batteries with an energy density of 3045 Wh/kg. By examining historical data on the energy densities of lithium-ion battieries and extrapolating it to the year 2030, an estimated energy density of 380 Wh/kg is attained. This is considerably lower than what is required. The best batteries today (2019) have a specific energy of about 280 Wh/kg, meaning the capacity of batteries would have to increase more than ten times to reach the needed density level of 3045 Wh/kg for the aircraft to be able to perform adequately.

Full textThis report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.
During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.
The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.
The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage. The simulation was used to see if the ideas that came up were going to work in reality. The simulation in Pro/Engineer made it possible to save a lot of time and make the work process more efficient.
Finally the interior were designed inside the vehicle body but most importantly it was built and adjusted to the human body. Important measurements and facts were collected with the help of the ergonomic program Jack. Which controls that should be included was investigated and the steering wheel became the central part of the dashboard since the vital functions are controlled via this unit. The speedometer and likewise functions where also moved to the steering wheel to improve the visibility.
The group was also set to explore other interesting details especially the engines. The engines that were chosen to the final concept where so called wheel engines. These engines are mounted inside the rims and can also handle the braking of the vehicle which makes a separate braking system unnecessary. The wheel engines had so many advantages that they became the obvious selection. But the vehicle was from the beginning set to be a hybrid and with only the wheel engines it was not. To make it hybrid, a second, smaller engine was put in, but only for recharging the batteries when needed. This engine is driven by gasoline or ethanol.

Full textThe purpose of this bachelor thesis is to design an electric powered commercial short-range aircraft that is set to take off in 2030 with reasonable technical advancement assumptions made. The aircraft is designed with the ATR 42-500 as inspiration and has therefore similar requirements. The aircraft has a payload of 5070 kg and cruises at 7600 m above sea level. It has a max speed of Mach 0.5 and a stall speed of 41 m/s. Climb rate is 560 m/min, takeoff distance is 1165 m and landing distance is 960 m. The conceptually designed aircraft has a range of 400 km that is approximately the distance London-Amsterdam and is able to carry up to 48 passengers in a two by two seat configuration. Batteries are expected to improve with 30 % during the next ten years resulting in a maximum takeoff weight of 19900 kg, where 3220 kg is battery weight. Fuel powered it has a maximum takeoff weight of 19200 kg and a fuel weight of 2900 kg. The power needed for propulsion was found to be 4.18 MW which would be equally divided over the engines that drive the two propellers. These are positioned one on each wing. The 26 m long aircraft is equipped with an unswept high mounted wing with a wingspan of 29 m and a wing reference area of 75 m^2. The horizontal stabilizer is 12 m^2 and the vertical stabilizer is 11 m^2.

Full textIs it possible for Saab's JAS 39 Gripen E to perform an airborne satellite launch? This question has been answered in this project based on a design-like equivalent fighter aircraft. The designed aircraft was developed at a conceptual level with the satellite launch mission as its starting point. The purpose of the project was to conceptually design an aircraft capable of performing an airborne satellite launch. The delimitations that were made were, among other things, that the designed aircraft would imitate JAS 39 Gripen E's abilities as much as possible. Another demarcation that was made was the geographical starting point of Saab's production in Linköping, Sweden. From the starting point in Linköping, a range of 800 km one way was set to the Norwegian Sea. There the aircraft was assumed to ascend to 16 km and then release the rocket. The rocketmass was calculated to 1530 kg including the 30 kg microsatellite that aimed to be launched to a low orbit around Earth. After performing the mission of launching the rocket, the aircraft will return to the starting point without refueling. The design of the aircraft was initiated in specific requirements for the aircraft based on data about JAS 39 Gripen E, taken from a data sheet published by Saab (2016). Some values that where not presented in the data sheet were assumed based on aircraft design literature. The requirements together with a mission profile led to a weight estimation of the aircraft's total weight, empty weight and fuel weight. From the weights and weight ratios, a constraint diagram was created based on the performance parameters; maximum take-off distance, rate-of-climb, cruise speed, constant velocity turn and maximum speed. This resulted in an optimal design point that gave a thurst-to-weight ratio as well as the wing loading. The conditions set a requirement on the engine and gave an estimated value of the wing area, which resulted in wing and tail design, wing geometry and center of gravity. The result of the designed aircraft shows that the requirements and values calculated is similar both in appearance and value specifications of the JAS 39 Gripen E. The conclusion is therefore, based on the mission profile, that it is possible for the JAS 39 Gripen E to perform an airborne satellite launch. Further work with the project may be to refine the weight estimates and specify the mission profile even more, for example with specific speeds. Further development of the project may be to design a converter or installation device to the fighter to be able attach the rocket and perform the mission in real.

Full textThis bachelor's degree project is about designing an airplane for high-altitude rocket launch.The rocket shall carry the satellite PICARD weighing 143 kg and will be fired up to low earthorbit (LEO).The aircraft's payload, the mass of the rocket, is three tons. The rocket is separated above theBaltic Sea, therefore, a range of 600 𝑘𝑚 and 30 minute endurance is required. For the rocketto reach the low earth orbit as quickly as possible, it is released 10 𝑘𝑚 above sea level.The aircraft is designed to mimic and perform as a fighter aircraft with high maneuverability.Therefore, the aircraft is assumed to have a climb rate of 2 km/min as well as take-off andlanding distance 460 m and 700 m respectively. The airplane cruise speed is set to Mach 0.9.Stall speed is assumed to be 200 km/h.This resulted in a total airplane mass of 19 𝑡𝑜𝑛𝑠, 66.2 𝑚2 wing reference area, 14 mwingspan, tail area of 13.8 𝑚2 and 24.1 𝑚2 respectively. The engines of the aircraft resultedin 2x F404-GE-402 turbofan jet engines manufactured by General Electric and giving theaircraft 158 kN propulsion.

Full textDenna rapport omfattar ett examensarbete utfört av två studenter vid högskoleingenjörsprogrammet i maskinteknik, inriktning produktutveckling och design på Tekniska högskolan i Jönköping. Uppdraget bestod av att ta fram ett produktförslag som underlättar hanteringen av inköpslista under inhandling vid dagligvaruhandel.Examensarbetet resulterade i ett slutligt koncept som tog fram i form av en fungerande prototyp. Produkten består av en platta, ett fäste för kundvagn, två snäpplister, ett lock och en pennhållare. Produkten har ett smidigt fäste som underlättar montering av produkten samt gör den anpassningsbar efter konsumentens önskemål.Uppdraget kommer ursprungligen från enmansföretaget Sirge AB som i sin tur hörde av sig till konsultföretaget Sigma Industry då företaget inte var etablerad inom produktutvecklingsområdet och därmed inte besatt den kompetens som behövdes för att utföra arbetet. Kontaktpersonen vid Sigma Industry ansåg uppdraget vara lämpligt som ett examensarbete. Sirge AB hade hittat ett glapp på marknaden för produkter som underlättar för konsumenter i dagligvaruhandeln. Önskemålet från kunden var att ta fram en produkt som kan fästas vid kundvagnen och underlätta hanteringen av en inköpslista. Detta för att undvika att hålla flera saker i handen samtidigt och istället frigöra händerna för varuplockning, scanning och dylikt. För att uppnå målet med arbetet utformades tre frågeställningar som sammanfattades med en huvudfrågeställning: Hur ska ett hjälpmedel designas för att hantera inköpslistor vid inhandling i butik och även vara flexibel för att klara olika typer av analoga eller digitala listor, konsumentägd och med rätt materialval? För att besvara huvudfrågeställningen arbetade projektgruppen efter metoden Bootcamp Bootleg. Arbetet inleddes med en förstudie som hade till syfte att undersöka intresset bland framtida konsumenter och utifrån detta ta fram en fokusgrupp. En marknadsundersökning gjordes även för att se vilka konkurrenter som fanns på marknaden samt för att se hur den nya produkten kan slå sig in på marknaden. Koncept togs fram med hjälp av metoden brainstorming och har sedan utvärderats och sållats genom metoderna SWOT och elimineringsmatris. De koncept som togs fram har sedan modellerats upp i CAD-programmet SolidWorks.Det slutliga konceptet består av en platta med en huvudfunktion som gör det möjligt att fästa en inköpslista. Produkten erbjuder även delfunktioner som förvaring av penna, telefon och ett extra utrymme för förvaring av andra föremål. Plattan och fästet till kundvagnen gjordes i CAD och togs sedan fram genom 3D-printing. Fästfunktionen för inköpslistan erbjuds genom snäpplister och är standardkomponenter gjorda i aluminium. Pennhållaren är gjord i ett läderlikt material och skivan som användes som lock har tillverkats i ett frostat plexiglas.
