Experimental And Computational Investigation Of Divergent Thrust Losses In Rocket Nozzles, Vaibhav Arya Graduate Engineer, Anushka Sunil Kapse Post Graduate Student 2022 Sandip University, MH, INDIA

Experimental And Computational Investigation Of Divergent Thrust Losses In Rocket Nozzles, Vaibhav Arya Graduate Engineer, Anushka Sunil Kapse Post Graduate Student

Graduate Research in Engineering and Technology (GRET)

The nozzle is a critical component of any rocket engine because it transforms high pressure and high temperature (with sluggish net velocity) within the combustion chamber into high velocity but low pressure. Individually, the molecules in the mixed propellants have rapid velocity in the combustion chamber, but directions are randomly pointing in all directions. A convergent-divergent nozzle, also known as a CD nozzle, is fashioned like a tube with two bulging ends and a thin part in the center. This structure/design provides the nozzle with a balanced shape. By turning the flow's heat energy into kinetic energy, the ...

Hybrid Rocket Propulsion Development And Application, Akshay Gharat Assistant Professor, Vinayak Hastak Graduate Engineer

Graduate Research in Engineering and Technology (GRET)

Satellite technology is advancing. Satellite propulsion requires several desired rocket properties. This is necessary for 1 kg of payload. Launch vehicles no longer need rocket engines. Application includes satellite movement, orbit transfer, and probe and lander propulsion. Space travel is inventive and exciting.

Research, production, and use costs must be decreased to make space transportation systems generally available. Security shouldn't be affected. Rocket propellants must be high-performing, non-toxic, and safe. Rocket engines have other parts. Restarting and throttling are crucial. These are inaccessible to solid rocket motors. Developing a liquid rocket engine is hard and expensive, but it can ...

Aerodynamics Of Forward Swept Wing., Muqeeth Sharif, Mohammed Abbas, Mukarram Hussain 2022 Institute of Aeronautical Engineering

Aerodynamics Of Forward Swept Wing., Muqeeth Sharif, Mohammed Abbas, Mukarram Hussain

Graduate Research in Engineering and Technology (GRET)

A forward-swept wing is an aircraft wing configuration in which the quarter-chord line of the wing has a forward sweep. Typically, the leading edge also sweeps forward. Forward swept wing is proposed with the goal of enhancing performance and controllability during high angle of attack perching maneuvers. Data is presented from a series of XFLR5 analysis to qualify the aerodynamic effect of forward swept over a range of angle of attack from -25º to +75º. Various graphs were obtained during this analysis which indicates that the forward swept wing configuration can achieve qualitatively different low cost perching maneuvers.


Application Of The Formal Design Of Experiments To Deformed Airfoil Testing, Alex Ligman 2022 University of Mississippi

Application Of The Formal Design Of Experiments To Deformed Airfoil Testing, Alex Ligman

Honors Theses

Traditionally, one factor at a time (OFAT) testing is used to accomplish wind tunnel
experimentation. OFAT testing is a process whereby one of the defined factors in the experiment is changed while all of the other factors are held constant. Afterwards, a new factor is chosen as the one to be manipulated, and the process is then repeated until all factors have been run through. Due to the possible cost-intensive and time-consuming nature of wind tunnel testing, formal design of experiments (DOE) has begun to be applied to wind tunnel experiments. In doing so, unique analyses can be made that ...

Online Pilot Model Parameter Estimation For Loss-Of-Control Prevention In Aircraft Systems, Frederick Schill 2022 Embry-Riddle Aeronautical University

Online Pilot Model Parameter Estimation For Loss-Of-Control Prevention In Aircraft Systems, Frederick Schill

PhD Dissertations and Master's Theses

A pilot is a highly nonlinear and incredibly complex controller whose responses are difficult to predict. Many accidents have occurred from pilot error before or after failures and almost always after entering areas of the flight envelope considered as Loss-of-Control regimes. If a pilot's inputs to the flight control system can be predicted, then the introduction of dangerous flight conditions can be readily avoided. Avoidance could take the form of a warning indicator or augmentation of the pilot's inputs. The primary difficulty lies in how to actually predict how the pilot will perform in the future.

Methods to ...

Liquid Engine External Pressurizer (Leep), Emily Armbrust 2022 The University of Akron

Liquid Engine External Pressurizer (Leep), Emily Armbrust

Williams Honors College, Honors Research Projects

The purpose of this project is to take the current liquid rocket engine test stand design and implement an external pressurant instead of utilizing the 2-phase oxidizer vapor to pressurize itself and the fuel. The purpose behind the design is because the team is limited with the current design concerning burn time due to the amount of propellant they can put in the tanks and the pressure it can reach. The initial pressure is currently not held since there is no external input of mass into the tanks, as the propellant is leaving. Adding an external pressurant allow for the ...

Astronaut Or Astronot?, David A. Gusis 2021 Purdue University

Astronaut Or Astronot?, David A. Gusis

Ideas: Exhibit Catalog for the Honors College Visiting Scholars Series

As space becomes more and more accessible to the general population, the terminology we used in the past to describe those who trained endlessly to become the pioneers of a new frontier is beginning to lose its meaning. Astronauts like Colonel Richard Covey have earned their title and to bestow it on others who haven't gone through the same training or have paid to visit space as a tourist is wrong. My hope is to provide the necessary background information about what it means to be an Astronaut and provoke thought about preserving the term and creating new terminology ...
