Hybrid Stol Aircraft Designed For Short Urban Operations, Toby Emch
Hybrid Stol Aircraft Designed For Short Urban Operations, Toby Emch
Discovery Day - Daytona Beach
Modern aircraft transportation requires security checkpoints, large terminals, and expansive runways to move people. However, what if we could place an airport anywhere, reducing land area, noise, and cost? Our design takes advantage of distributed electric propulsion powered by a hybrid engine to take off and land a STOL transport aircraft in a short distance. Our design process includes calculation of constraints, lift calculation using a blown lift takeoff, and verification of stability coefficients. Using a high-lift wing design, the aircraft supports a battery and fuel weight while keeping the required thrust low. It supports up to 7 passengers and …

Boeing 787 Freighter Conversion: Structural Redesign And Enhanced Cargo Operation, Darien Lopez
Discovery Day - Daytona Beach
With the continued expansion of global supply chains, demand for airfreight is rapidly increasing. As older cargo aircraft approach the end of their service life, the Boeing 787 freighter variant emerges as an ideal candidate to address this growing market demand. To facilitate its conversion from passenger to freighter configuration, modifications included the addition of a cargo door and adjustments to the cabin floor, allowing for efficient cargo loading operations. The structural components, including stringers and longerons, were specifically sized and strategically positioned in both the cargo door section and throughout the rest of the fuselage to accommodate the anticipated …

Regional Amphibious Aircraft Preliminary Design, Giovanna Ucles
Discovery Day - Daytona Beach
This project presents the preliminary design of a regional amphibious aircraft, aimed at servicing a variety of missions in areas with limited infrastructure. Currently, aircraft options for operations in challenging environments are limited, with most designs relying on float-like structures. This new design reintroduces the flying boat concept, offering reduced drag and improved operational efficiency. Two configurations are proposed: a 19-passenger version with a range of at least 350 nautical miles, and a 10-passenger version with a range of at least 980 nautical miles, both achieving a minimum cruise speed of 150 knots. Hand calculations were employed to assess key …

Trainer aircraft present a unique fuel efficiency issue – the aircraft will almost never fly at its most efficient configuration simply due to the nature of pilot training. Taking this into account, Project Eggroll will be tackling this issue at the beginning of fuel consumption, rather than optimizing aerodynamics, and will be incorporating a hybrid propulsion system in a next-generation trainer aircraft to reduce fuel consumption, noise, and cost for consumer. After filtering through multiple potential configurations for the aircraft and powertrain, the ER-01 trainer aircraft’s final design has been refined to a high wing aircraft with an all-movable horizontal …
Internal Structural Design For Low-Cost Unmanned Fighter/Interceptor Aircraft, Andrew Zubyk
Internal Structural Design For Low-Cost Unmanned Fighter/Interceptor Aircraft, Andrew Zubyk
Discovery Day - Daytona Beach
Akriveia Aerospace is focused on the design of a high strength and efficient structure to accommodate the small size of Akriveia Aerospace’s Accipiter aircraft while ensuring the structure’s ability to sustain the required loadings. Emphasis is placed on wing spar, fuselage bulkhead, bulkhead-to-spar bracket, skin, and spar web sizing; as well as the fasteners used to join the structural components. The Accipiter was inspired based on historical and modern fighter/interceptor aircraft, such as the F-16 Fighting Falcon and F-35 Joint Strike Fighter. Preliminary sizing was conducted using conventional evaluation techniques; future aims involve validation using Finite Element Analysis. Due to …

Hybrid-Electric Regional Passenger Aircraft: Emphasizing Environmentally Impactful Technology, Annabelle Stube
Discovery Day - Daytona Beach
The aviation industry has significant negative impacts on the environment through greenhouse gas emissions and noise pollution. As small passenger aircraft tend to have more emissions per passenger mile than larger aircraft, this project aims to design a new hybrid-electric propulsion aircraft to be an innovative environmentally conscious option for short-range, limited-passenger flights. The design process focuses on constraint analyses, high stability, emission and noise reduction, uniqueness and marketability, and utilizing upcoming propulsion systems. Several new propulsion system options were assessed to prioritize viability and power and minimize environmental impacts. The hybrid-electric propulsion system and 12-passenger capacity were decided to …

Wing Structure Design The Ramp-200, Nicholas Hillburn
Discovery Day - Daytona Beach
This project focuses on the design of the wing structure to increase fatigue resistance and lessen the shear force across the skin of the wings, while maintaining the structure’s stability and soundness. The designed wing structure will be optimized to account for the proposed weight and endurance of the aircraft. The overall wing shape and size was defined using preliminary design methods and optimized for efficiency at Mach 0.9. The main structures were sized using calculations that were programmed into MATLAB and supported by hand calculations. Finite element analysis was used to verify sizing, and the structures were assessed using …

Discovery Day - Daytona Beach
This project focuses on designing the wing structure of an interceptor aircraft to withstand sustained supersonic flight and provide sufficient fuel storage for extended operations. The aircraft and structure were designed according to the AIAA Homeland Defense Interceptor request for proposal (RFP). Sizing of structural components was performed utilizing hand calculations and an idealized shear box approach focused on maximum aircraft limit loads. Based on these preliminary calculations, different wing structural components such as spars, ribs, stringers, and attachment points were designed using computer aided design (CAD) software. Finite element analysis was used to verify results and structural integrity of …

The growing interest in Scramjets for achieving sustained hypersonic flight has given rise to numerous computational models to obtain solutions as close as possible to experimental data, assisting with making the design process of modern Scramjet’s with different propellants and cavity designs less costly. However, Scramjet engines pose significant challenges for computational modelling due to the need of accounting for large- and small-scale turbulences but also solving turbulence chemistry interactions in compressible flow regimes. A promising approach has been through using high-fidelity turbulence-combustion models which greatly assist with capturing detailed chemistry, account for small scale turbulence and the complex flow …
