The UCI RP Fins Design and Integration works to design and create a plan of manufacturing of fins for the UCI Rocket Project’s Preliminary Test Rocket. For the past several years, the team has had a multitude of successful launches, all with the incorporation of a fin design.  The Fins teams will be continuing the tradition of launching a rocket with fins by designing the fins geometry, selecting the material and components to manufacture, and developing a mounting method to attach the fins onto the fuselage of the rocket. 

Integrating the words tension and integrity, tensegrity utilizes adjustable tension among one-dimensional interacting members in order to create different three dimensional structures. This project aims to create the first morphing wing at UCI using a tensegrity mechanism. The wing will be able to change airfoil shape on demand, in order to produce more efficient aerodynamic properties based on flight sections (takeoff, cruise, and landing). Split into two sub-teams, simulations and structural, the team will work toward creating and building a functional prototype of the tensegrity wing, and test the prototype in UCI's wind tunnels to verify results of more efficient lift, drag, and pressure distributions than conventional wings. 

The UC Irvine Intelligent Ground Vehicle is a project in order to implement skills learned in university courses by designing and testing a self-automated ground vehicle that can navigate an obstacle course autonomously. The purpose of the project is to be able to develop a vehicle that utilizes multiple sensors to self navigate while carrying a payload. 

UAV Forge is an interdisciplinary team that competes in the Student Unmanned Aerial Systems Competition (SUAS) hosted by the AUVSI. This competition involves teams programming and designing both an unmanned ground and aerial vehicle to undergo missions laid out by the rules.

Background:

Our design basis is to make modifications in the previous’ teams design in an effort to make the automated assay more reliable and user-friendly. The general concept of the automated assay is to create a device which autonomously or semi-autonomously administers a malaria test using reagents to a similar extent to a high-priced biometric assay. The assay has to give appropriate responses to an assortment of reagent based test. While also reporting the test results to its test users through a convenient smartphone application. 

Global landscape:

Although the previous teams’ intentions are unknown, from the very beginning our team had one idea in mind. Malaria is a disease rampant in third world countries — similar to a host of many. If doctors are able to test their patients sooner and faster, their treatment would be significantly more effective. For that reason, we use cheap and easily assessable parts which...

BACKGROUND:

The CubeSat team at UCI is a student-led effort to launch a 2U nanosatellite into orbit to test two UCI research payloads. The satellite operates with five subsystems (Power/Payload, Communications, Avionics, Structures/Thermal, and Systems Engineering), in addition to housing two payloads. The first payload is a variable emissivity device (VED) that will be tested as a thermal regulator, and our job is to test its performance in various degrees of solar exposure and at varying adjustable emissivity values. Similar materials to the sample are hoped to be used as a cheap method of thermal management on future spacecraft. The second payload is in collaboration with the ASPIN lab at UCI. The satellite will carry a transceiver meant to function as a transmitter of a “signal of opportunity”, helpful in researching novel navigation methods in the absence of or in place of a traditional GPS signal.

OBJECTIVES:

UCI Cargo Plane participates in the Society of Automotive Engineers (SAE) Aero Design West Competition. This competition provides engineering students exposure to real-life engineering challenges in the aerospace industry. The goal is to create a bush plane design that can operate from short runways while carrying outsized cargo. Students are expected to perform trade studies to find a design solution that will optimally meet the mission requirements. The types of payload these aircraft are required to hold are soccer balls and steel plates. During the competition, teams are expected to load and unload soccer balls and steel plates in under a minute. For this reason, the design should account for easy loading accessibility. These design factors test the team’s ability to exercise time management, stay within budget, and ultimately build a plane to meet the goals of the competition.

Introduction

Aeronautics, Dynamics, and Control Laboratory (ADCL) is an  interdisciplinary lab focusing on the modeling and analysis using the rigorous mathematical tools of both Geometric Control Theory and Unsteady Aerodynamics to develop non-intuitive new engineering applications. ADCL developed new control algorithm which enables the airplane to achieve high rolling maneuverability in stall. This new rolling algorithm will solve a challenging problem in the aerospace industry, where Airplanes lose the rolling controllability in stall.

LIBRA stands for Lie Bracket Rolling Augmentation Mechanism. Lie Bracket is the  geometric control tool which has been used to develop this algorithm. this name inspires the extended freedom by enabling flying in the stall regimes. LieRoll was another name proposed, but was never selected.

Goal

The goal of this project is to demonstrate experimentally the control authority given to the airplane in stall regimes. The experiment is divided into three phases as follows:

Phase...

The focus of this project is to design and build a robotics kit that introduces and is inclusive to students typically underrepresented in STEM to engineering.
To achieve this, students will design a cost-effective robotics kit that incorporates many introductory level features and an evidence-based curriculum that a middle/high schooler can safely construct with assistance.

Sustainability is an increasingly important consideration for engineers throughout the world. With the increases in global temperature, engineers are looking at renewable energy generation to combat climate change. California has already enacted the SB-100 Renewables Portfolio Standard Program, which is attempting to transition 100% of California’s electricity to renewable sources by 2045 (SB100).  Solar and Wind Energy are essential components in this fight against climate change. Current utility based renewable energy production demands vast investment in land and capital while inducing irreversible damage to the ecosystem. On the other hand, The Hybrid Renewable Energy System (HRES) aims to reduce land use while it addresses the growing demand in renewable energy.

The purpose of ReTouch is to create a device that assists post-stroke patients to regain their sense of touch. The device contains two modules, where one module moves the patients’ index, middle, and ring fingers on their paralyzed hand and the other contains buttons allowing them to use their healthy hand to press and match the fingers that are being pushed. The device additionally contains a musical game corresponding to activity done on the modules to improve patients’ sense of touch over time.  

HydroCube is a electrolysis device that can be connected to a residential solar pannel system in order to convert and store any excess electricity in the form of hydrogen. Currently when a homes battery is full the rest of the electricity produced by the photovoltaic cells is not stored and therefore is wasted. With stored hydrogen we could begin to explore the posibility of using hydrogen in a residential setting or to power a generator to feed back to the battery when there is low sun coverage. 

Background

New forms of renewable energy have surfaced in the past years.Hydrogen fuel cells are a form of renewable energy that is easily accessible since hydrogen is the most abundant element in the universe, and do not cause pollution or danger to our environment as they do not release greenhouse gases as opposed to burning fossil fuels.The fuel cell drone project uses a fuel cell battery as a source of power for a flying robot that can be remotely controlled or fly autonomously through software-controlled flight. 

For this particular project, we will be researching the fuel cell efficiency in a drone that we will design and build ourselves. Groups will be building a structure for the drone and assembling electronic parts for use throughout the experiment, while keeping the fuel cell as the focal point of this project. The advantages of the fuel cell lie in longer flight times, quick...

The UC Irvine Rocket Project aims to push the boundaries of collegiate rocketry and the development of liquid propellant rockets. Our project strives to prepare students for successful careers in the aerospace and defense industry. In 2017, Base 11 became a partner of the UCI Rocket Project. Their gracious donation enabled the construction of our rocket lab. During the Fall quarter of 2019, the team has scheduled and completed a successful static test fire to experimentally verify our first engine design. An experimental combustion test is a critical first step in designing a full rocket system as well more efficient, higher performance engines.

Anteater Electric Racing is an Engineering Design Project consisting of Mechanical, Aerospace, Electrical and Computer Engineers tasked to design, build and test a Formula SAE Electric Racecar. The team of 60 Engineers will enter their 2020 Ampeater Racecar into the Formula SAE California  at the Auto Club Speedway in Fontana this June againt 110 other universities. At the Winter Design Review, the team will display their built Racecar for review and will be excited to present the specifications of this year's build. 

Background

Flow field bipolar plate is a very important part of the proton-exchange membrane fuel cell(PEM). They are designed to provide an adequate amount of the reactants (hydrogen and oxygen) to the gas diffusion layer (GDL) and catalyst surface meanwhile remove the generated water. In general, the flow field is grooved in bipolar plates featured by hollow channels with a cross-section dimension of ~1 mm. Using hollow channels increases the thermal resistance and electric resistance in the fuel cell, thereby reducing cell performance. In this project, we plan to design a proton-exchange membrane fuel cell using porous media flow field, which fills channel space by porous media. We will investigate fuel cell performance and flow conductance for this new flow field design. The porous media selection will be optimized, in terms of parameters including porosity, tortuosity, pore size, and mechanical properties, for high-performance fuel cells.

Goals and objectives

Our goal...

Spacecraft Thermal Management Systems (STMS) is an undergraduate, interdisciplinary research/design project that works to develop an electrochromic cell for space applications for Cube and Nano Satellites. This device will act as a method of controlling heat from going into and out of the satellite through a color change, which affects how much heat is being let in. Such spacecraft are not exposed to a constant heat flux from the sun as a result of low Earth orbit. This device is special since the amount of color change can be modified to let in the proper amount of heat necessary for the spacecraft to operate.

The device works through a redox reaction pairing of nickel oxide and tungsten trioxide based films. When electrons are removed from each film, the nickel oxide will color to a dark brown and the tungsten trioxide will bleach to a clear coloration. Similarly, when electrons are added to each film, the nickel oxide will bleach to a clear coloration and the tungsten trioxide will darken to a blue coloration. When these thin films are combined, both pairs will either darken or bleach at the same time, forming the device.

The primary objective of the High Heat Flux project is to design, develop, and fabricate a thermal management
system capable of producing and dissipating high heat fluxes/loads exceeding 500 W/ cm^2. University of California, Irvine, Mechanical and Aerospace undergraduate students are tasked to designing and building a thermal system capable of generating and dissipating high heat fluxes. Currently, our system consists of a copper rod, a vacuum chamber, thermocouples, LN2, and a cooling system we are in the process of designing.

The Flight Simulation Chair is a robotic project with the objective of simulating the experience of flying a fighter jet. The project is controlled by one Arduino Mega 2560 microcontroller, two pneumatic pistons constantly supplied at 50 psi of compressed air, and moves in two degrees of freedom (roll and pitch). The unique feature of this project is its option of playstyle: Remote Control (RC) and Virtual Reality (VR). For more information, please see the full description on the project page.
