Case Study: Analysis of Hydrogen Flow Control Valve Issues in Aviation

This case study focuses on the challenges associated with hydrogen flow control valves in an aircraft, particularly the unexpected flow and subsequent issues. The analysis delves into the problems of the flow, the impact of valve failures, and the necessity of thorough inspections and management strategies. The study discusses the need for open communication and collaboration among various organizations to ensure comprehensive problem-solving and the availability of relevant information. The case emphasizes the importance of addressing potential mechanical failures, cracked valves, and the complexities of assembly and resupply schedules. The research highlights the need for proactive measures, including non-destructive evaluation techniques and adapting solutions to environmental factors. The primary goal is to offer insightful solutions and management strategies to avert future issues in the aircraft.

The case study describes the flight flow control regulator issue; the controllers monitoring is
important because it realizes excess amount of hydrogen flow from one of the Aircraft's engines.
The flow was unexpected and didn't the response to an automated command from the system.
The main concern was even after the irregularity if flights launch, there was the smooth launch
of flights but even after the control regulators for three flow work in the concert to maintain the
hydrogen tank pressure. But the crashed were due to the electrical failure or a mechanical failure,
which was due to a failure of broken valve.
To rectify the above problem, management has to do the analysis to ensure the safety of future
shuttle mission; there can be possibility default in management or technical community. Thus
analysis gives the possible solution for future missions implicated projects.
To make analysis easier there should be open doors for the problem as well as advice from all the
multiple organization, so that they will get all the possible solution for their problem and there
will be an availability of all relevant information for organizations to sort-out the approve or
delay future shuttle flights. There was a number of advice for the head as John MaManamen the
chief engineer of space shuttle program, said there should be proper inspections done, and some
x-rays should be done that where the vehicle landed.
The another problem associated with flight delay is Complex Assembly and Resupply Schedule:
The fluctuation in programs schedule made it very difficult for to launch salve if they were
tightly integrated with international ISS resupply launches by the progress, ATV and HTV
vehicles which represent a very complex evident for the Aircraft and station programs.
Broken Hydrogen Flow Control Valves which are very important part of space shuttle orbiter,
organization have to take the decision whether to remove the valves from the orbiter for the
inspection or to take an x-ray of them in place of the vehicle. Finding that there is cracked valve
can result in high-cycle weakness, and the reason for this crack can be the unfavorable
environment, and the consequences of breaking valve in flight will be the worst case.
The sometime technical team worked on the problem from multiple angles, which include
fracture mechanics, structural dynamics, CFD.
There is a number of potential solution to deal with the cracks in a valve; the initial efforts relied
on the visual inspection and number of non-destructive evaluation techniques including dye
penetrant inspection and scanning electron microscope.
Thus, the research allows organization to do the necessary analysis and keep the door open for
open communication in all the multiple organization so that they will get all the possible solution
for their problem and there will be the availability of all relevant information for organizations to
sort-out the approve or delay future shuttle flights. The future research can be on making salve
according to keep in mind the weather condition, as the hydrogen flow control valves cracks due
to landing in an unusual environment. There should be proper management in the complex
assembly and resupply schedule for smooth supply of aircraft.
