What is mass structure?

0

The structure mass scale is the rate at which the cost of the structure changes relative to the rate at which the empty mass of the structure changes. A low value means that there are large economies of scale, so that large structures are relatively inexpensive compared to small structures. A high value means that there are small or no economies of scale, so that large structures are relatively similar in cost compared to small structures. This would be the case if extremely automated manufacturing was used, where the cost of the structure is close to the cost of the raw materials. In rocket cost the structure mass scale is used along with empty mass, exhaust velocity, structure exhaust scale, structure tensile scale, tensile energy and ten ton structure price to calculate the structure cost. structure cost = ten ton structure price * pow( ( empty mass / 10,000 ), structure mass scale ) * pow( ( tensile energy / 205,000 ), structure tensile scale ) * pow( ( exhaust velocity / 3,330 ),
