26 Spacecraft Engineering Questions And Answers

2⟩ Do you know what is performance analysis in spacecraft engineering?

Performance analysis in military programs include responsibility like analyzing aerodynamics impacts which effects from external modifications, developing mission profiles based on requirements from the customer, performance data of the mission which includes take off and landing details, en route and mission data performance. Analyze the configurations using the dynamics, which are fluid and computational. Additional task may include support for wind tunnel planning for test flight. Documentation, test support, data analysis should be done on regular basis. Co ordination of aerodynamics with multi discipline teams and data should be provided for support flight management system or mission planning software.


3⟩ Can you please tell me the responsibility of the spacecraft operations, dynamics and controls?

People working on these areas as spacecraft engineers should have familiarity and exposure to NASTRAN and MATLAB with knowledge on space environment and modeling of flexible dynamics. These spacecraft engineers will be responsible to work in the areas of structural control, momentum control, line of sight (LOS), spacecraft mission design, control of space boards payloads and operational engineering.


4⟩ Tell me how static electricity affects radomes in spacecraft engineering?

Under conditions of low humidity the static electric charge on a radome surface can build up to a very high potential. Severe spark discharging as a result of this condition will create radio interference over a wide band of frequencies. Physical charge may also occur. The electrical discharges chip the paint and often burn small pits or pinholes in the radome. These small surface punctures created by the arcing rapidly increase in size as carbon deposits resulting from the charring encourage further strikes. If this condition is left unchecked, eventual damage to the radome will result from water penetrating through the radome surface into the radome core.


7⟩ Do you know how to reduce noise as a spacecraft engineer?

In order to be able to reduce disturbing noise levels, it is very important to identify two key elements. The first element is the source of the noise. The second is the frequency of the noise. Typically a vibration mount designed in accordance with vibration.


8⟩ Please tell me about flow control in spacecraft engineering?

Flow control is also called optimized production technology, focuses on the efficient flow of material through the production process. The philosophy of flow control focuses on bottlenecks. Flow control applies well where maximum productivity is required.


9⟩ Please define just-in-time in spacecraft engineering?

Just-in-time or lean manufacturing is a production management philosophy built around the continuous reduction of waste. It is suited for businesses where production efficiency is key. Anything that interferes with productivity is waste and, therefore, the enemy under JIT systems. Techniques that support JIT philosophy include reducing inbound inventory by creating supplier delivery schedules, minimizing outbound stock with customer delivery schedules and constant work in-house reducing scrap material and wasted man-hours. These techniques improve cash flow and maximize sales margins.


10⟩ Define spacecraft engineering?

Spacecraft engineering is the primary branch of engineering concerned with the research, design, development, construction, testing, science and technology of spacecraft.

It is divided into two major and overlapping branches:

☛ Aeronautical engineering

☛ Astronautical engineering.


11⟩ Do you know what is materials requirement planning in spacecraft engineering?

A given quantity of finished goods requires a given quantity of raw materials and components to make them. Materials requirement planning systems are computerized tools that manage when materials must be ordered to supply production at a later date. Materials requirement planning is effective when output quantities are known. Small business owners are often their own materials requirement planning systems, storing the information needed to supply production in their knowledge and experience. Activities such as computer tracking inventory and forecasting demand are materials requirement planning activities.


12⟩ Give me an example of hydraulic unit in spacecraft engineering?

Gas charged air-stair deployment dampers can become too weak in cold temperatures, causing the airstair to slam down into the deployed position. Conversely, they will become overcharged in very hot conditions, causing the door to hover short of the fully deployed position. A hydraulic unit will perform smoothly in both temperature conditions.


17⟩ What do you think about the future of research in hypersonic flow?

The future research in hypersonic flow will be focused on development of better CFD tools and physics-based models to support hypersonic air-breathing and planetary entry vehicle technologies. A combination of ground testing and occasional flight testing will provide opportunities to demonstrate these technologies as well as to validate analysis tools.


20⟩ Tell me about the testing done in spacecraft engineering?

The testing of small rocket engines and entails development by researching on spacecraft. They are responsible to perform and experiment on laboratory facility, which is dedicated to aerospace. One should be capable of solving problems by applying knowledge by solving problem of the research done. They will be working with technical team of researchers and they should have ability handle projects alone.
