Typ-I-Diagnostik von Berufssubstanzent is investigated using optimal control theory. Ascent trajectories are optimized for different combinations of spacecraft structural factor and engine specific impulse, the optimization criterion being the maximum payload weight. Normalized payload weights are computed and used to assess feasibilit

The problem is formulated using a simplified version of the restricted three-body model and is solved using the se

The optimization problem is formulated as a mathematical programming problem: the total characteristic velocity (the sum of the velocity impulses at

Besides the trajectory design, models are given that relate (i) the propulsion mass to a desirable increase in the mass flow for the rocket engines and (ii) the structural mass of the fuel tanks to a desirable increase in the propellant mass.

The first part describes how to build an integral model, which can be used for simulating the rigid motion as well as the flexible motion of the aircraft. The result is a system of nonlinear equations of motion. The second part analyzes the dynamic properties of a sample aircraft by
