Dry matter

Dry mass is a key concept in aerospace and refers to the mass of a spacecraft or other space system without taking into account propellants or other consumable liquids and gases. Here are some important aspects and properties of dry mass:

Definition and meaning

The dry mass is the mass of a spacecraft or system when all propellants, pressurized gases, hydraulic fluids and other inert liquids or gases have been removed. It includes only the structural mass and permanently installed components.

The dry mass is a decisive parameter for the planning and design of spacecraft. It influences the performance, payload capacity and efficiency of the spacecraft.

Properties of the dry matter

Structural components

The dry mass includes all structural components of the spacecraft, including the fuselage, engines, avionics and other fixed equipment.

Payload capacity

The dry mass is a decisive factor in determining the payload capacity of a spacecraft. A lower dry mass makes it possible to transport more payload or increase the efficiency of the spacecraft.

Performance

Dry mass affects the performance of a spacecraft, including its maneuverability, acceleration and range. A lower dry mass can improve performance.

Design optimization

In the development of spacecraft, dry mass is often optimized to maximize efficiency and performance. This can be achieved through the use of lighter materials, improved construction techniques and innovative designs.

Safety aspects

The dry mass is also important for safety reasons. More precise knowledge of the dry mass makes it possible to ensure the structural integrity and stability of the spacecraft.

Calculation and monitoring

The dry mass is determined by detailed calculations and analyses that take into account all structural components and permanently installed equipment. These calculations are based on technical drawings, computer models and material properties.

Dry mass monitoring is a continuous process that is carried out throughout the development and operational phase of a spacecraft. This includes regular inspections, tests and analyses to ensure that the dry mass meets the specifications.

Conclusion

Dry mass is a key concept in aerospace that has a decisive influence on the planning, design and operation of spacecraft. By optimizing the dry mass, the efficiency, performance and safety of spacecraft can be improved, which in turn creates the basis for successful missions and applications.
