BC = ballistic coefficient (kg/m2) m = entry trajectory mass, Rover + Lander + Aeroshell (kg) CD = drag coefficient. A = cross-sectional area of Aeroshell (m2) ... The chamber pressure is a typical number for rockets of this type. A higher chamber pressure will give better performance. We used this expansion ratio because better performance is ...

Ballistic Coefficient
(Streamlined / Blunt-ended) has higher ballistic coefficient. (Streamlined / Blunt-ended) will experience more deceleration early in the entry. (Streamlined / Blunt-ended) can achieve better accuracy because it spends _less___ time in the atmosphere. 7. List three methods of dissipating the heat generated during re-entry: __Heat Sinks_____ b.

The ballistic coefficient a variation is the inverse of this in some systems) is generally used to lump the mass, area, and coefficient of drag values together. It will vary, sometimes by a large factor. Several initiatives are examining the time-rate of change for this combined parameter without looking at the individual contributions.

Note the last entry of Table T-8 deals with the Beta coefficient. The Beta coefficient for LM is 0.80. The Beta coefficient is market risk of the stock. So with a Beta coefficient of 0.80, LM stock is 20% less risky than the average risk stock (the average risk stock has a Beta coefficient of 1.00) Figure F-13 shows the Liquidity Ratio Trend ...

The impact velocity is dependent on the entry velocity (at the top of the atmosphere) and the ballistic coefficient, which determines how much the spacecraft will be slowed by the martian atmosphere. Spacecraft sent to Mars in the future will have a range of ballistic coefficients, and entry velocity will be different for each launch ...

A complete test series for the ballistic limit consists of individual ballistic tests being conducted on a number of individual test items. The conditions that constitute the dividing line between a partial penetration and a complete penetration shall be specified in other standards and specifications.

A bullet's ballistic coefficient then relates the drag on any bullet to that of the standard bullet. The drag model to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.
