Assignment: Design a Spaceship

Requirements - It must:

• attain mission with payload and/or passengers.
• be hands and economically produced and maintained.
• be reusable and accept every bit few stages as possible to reduce cost and recover expensive materials.
• pass all engineering and flight tests.
• BE Price Effective.

Engineers at NASA'south Langley Research Center must consider many questions every bit they blueprint the adjacent generation of space vehicles. Their arroyo is not CAN they do it, merely HOW tin can they do it BETTER than earlier and more cost effectively.

One of Langley's jobs is to create new and innovative technologies to see the challenges of space flight and lower the cost of future space missions. With technological advances in many areas and expanded needs and capabilities of space missions, NASA researchers face unlimited possibilities. Equally they work through a series of steps from concept inception to full-scale design, they may hit stumbling blocks and be forced to retrace their steps and sometimes even showtime over. At every turn, nonetheless, they are pioneering their way through scientific discipline and engineering, turning theories into reality. Their designs must pass concluding qualification tests and exist proven price efficient. Only then volition they exist considered for service.

What is a Spaceship

A spaceship is designed to travel in infinite and may be launched from World by a launch vehicle. It may carry a payload to accomplish a mission with or without people and return to Earth.

HL-20. This personnel transporter has fabricated information technology to
the mock-upwards stage and awaits further approval before
beingness built.

5 STEPS TO BLASTOFF

Pace ONE: Mission Purpose

What is the purpose of the mission? That question begins the avalanche of other questions which lead toward design requirements. What is the payload, how big is it, how much dispatch and entry heating must it take? Once these, and many more requirements are decided, a study is done to decide whether the mission performance requirement tin can exist met.

Step ane. The HL-20 was designed by NASA Langley
to carry astronauts dorsum and forth to the space
station and to serve as an emergency render
vehicle while they are there.

STEP TWO: Design

The nature of the payload and its special needs assistance determine the design - shape, size and configuration - of the space vehicle. If people are going, in that location are obvious unique requirements, such as seating capacity, archway and exit hatches and access to certain systems. The configuration of the spacecraft must provide for all of the support systems, such as communications, electrical systems and life support.

Step two. Researchers considered various
configurations for the HL-xx. External admission to
subsystems, to allow for piece of cake maintenance, and
enough room for eight passengers were ii height priorities.

Step Three: Analyses

NASA Langley engineers must determine the craft's full general operation earlier launch and upon its return. They must analyze the aerodynamic, or air period, characteristics of the configuration, also as monitor structural stress, effects of high speed, heat tolerances and the performance trajectory, or course information technology flies to space and back.

Engineers must consider appropriate new materials for the spaceship that could minimize cost and weight. Every pound of extra structure may have upwardly to 10 pounds more in total launch weight to get it into space - and back. And every pound of construction raises the cost of the mission.

Step iii. The HL-20 design was analyzed for
aerodynamics in wind tunnels and by computer,
to understand how the air would period around
it and would bear upon its flight into space and dorsum.

Footstep 4: Testing

In one case the spaceship has been designed, it must be certified for flying through a series of performance, vibration and thermal tests. It is now fourth dimension to exam the actual structure with models of the design.

It is not necessary to build an entire spaceship for initial testing. Instead, engineers build and examination the individual components. A wing, for instance, may exist subjected to tests that are non advisable for any other function of the vehicle.

After initial testing, whatever parts of the spaceship construction or internal systems which practise not meet performance requirements are then redesigned and retested.

Step 4. Water entry tests using a small-scale
model of the bodily design.

Footstep FIVE: Fabrication

In one case a final design passes initial tests, a full-scale model, or mock-up, is fabricated in fiber drinking glass or other inexpensive materials. Afterward, an actual paradigm, called the flying model, may be built so tested to assure the quality of design. If information technology passes many hours of tests including a series of experimental flight tests, it is ready for production and operation.

Pace five. A mock-up of the interior design of
the HL-20 enables real astronauts to
determine if they can move and function as planned.

Side by side Generation Has Arrived

Current space missions require a launch vehicle with rocket stages to become a spaceship such as the HL-xx into space. As we approach the new millennium, NASA Langley is using its experience to help manufacture develop and introduce the next generation of space vehicles. One of its top priorities is a fully reusable spaceship, a launch vehicle, which would fly to space and dorsum as a single unit of measurement or single stage. Depending on the mission, the reusable launch vehicle could back up sophisticated, high-precision, deployable instruments for specific scientific research. A image of this vehicle, the 10-33, is slated to fly in 1999.

NASA Langley engineers besides take an active role in the design of the International Space Station, the components of which are currently existence built.

Summary

NASA Langley's current evolution of next generation launch vehicles follows a systemized course from inception to prototypes to flying vehicles. With the goal to reuse vehicle components and eliminate multi-stage rockets, NASA Langley researchers have brought united states of america into the 21st Century and volition continue to meet the ever changing and expanding requirements of space missions.
