Payload, defined

It appeared that the experimental conditions used in the present study favoured the formation of microspheres of a new type which could be defined as film-type microspheres. They consisted of spherical micromatrices comprising an internal void space and a polymeric membrane of variable thickness where the drug is dispersed in either a molecular or a solid state depending on the payload. 

Space vehicle mass The space vehicle mass is defined as the wet (with propellants) and dry (without propellants) mass of the integrated payload and spacecraft... 

The second condition can be expressed in terms of the ratio D of the energy in rotation to the energy in the plasma payload , both measured at peak compression. This is shown graphically in Figure 3, where the parameter A is the ratio of the mass of the driving mechanism to the mass of the liner, y is the polytropic coefficient of the payload, and b is the thickness parameter defined previously. 

We define the mechanical economic efficiency parameter as ton-mile/gal (tons of payload and vehicle)(miles transported)/(gallons of fuel consumed). Clearly the larger this parameter, the more efficient the vehicle from the standpoint of energy efficiency. 

The first step is to define the objectives and scope. The objective is to calculate the risk of launching the payload. Is it sufficiently risky to ground the system and not launch If so, what can be done to make the risk acceptable and go forward with a launch ... 

The payload relates to how much weight a robot can lift, and speed relates to how fast a robot can position the end of its arm. The acceleration of a robot refers to how quickly an axis can accelerate, and accuracy relates to how closely a robot can reach a commanded position. We can define repeatability as how well the robot will return to a programmed position. 

A systematic project activity to ensure that a space payload intended for flight has sufficient structural integrity as to present no critical or catastrophic hazard. This activity also ensures quality of performance in the structural area for any payload. Central to the program is fracture control analysis, which includes the concepts of fail-safe and safe-life, defined as follows ... 

The SystemUnitClassLibrary allows specifying the capabilities of solution equipment objects that can be matched with the requirements of objects defined with the role classes. A system unit class describes a physical or logical object including the concrete technical realization and internal architecmre. For example, a System Unit Class KRIOOO that matches with the role class robot may describe attributes of the KUKA KR 1000, which has a payload of 1,000 kg. Thereby system unit classes form a multi-level hierarchy of vendor-specific objects that can be instantiated within the InstanceHierachy. 

One measure of propellant performance is specific impulse,, which is defined as pounds of thrust delivered by a flow of one pound per second of gas through the rocket nozzle. While the specific impulse of operating rockets has increased about 25 since the Second World War, theory indicates a further possible increase of approximately 50 [31. Liquid-propellant rockets in use today, LOX-gasoline systems, are achieving a specific impulse of 264 Ib-sec/lb. Theoretical Jgp possible with liquid-fluorine—liquid-hydrogen systems is 373 Ib-sec/lb. Small increases in are important in terms of range and payload. As an example, it can be calculated that a increase in of a typical ballistic missile can result in a 9 increase in payload or a 6 increase in range [4].
