Book Description
In the 1970s recent college grad Char flees to the idyllic Pennsylvania-Dutch countryside to consider her future. Staying with a Mennonite great-aunt, she meets Amish bad boy Uri Stoltzfus, who agrees to serve as her guide to the Plain culture. Both Char and Uri have hard choices to make about the values they will embrace in this coming-of-age novel set against the backdrop of a turbulent decade. Feminism, racism, the Vietnam War, more permissive attitudes toward sex and drugs, and new types of music collide with a way of life unchanged for centuries. Char also meets another great-aunt whose very existence proves an affair between Char's great-grandmother and an unidentified lover. Who was he and why did he not assume responsibility for his daughter? Char hopes that finding an answer to this family mystery will help her solve her own dark secret.

Book Description
A general method is presented for solving the problem of heat-shield response in the stagnation region of a charring type ablator. The analysis is actually for the stagnation point of an axisymmetric blunt body, but it is a valid approximate method for calculations in the stagnation region of any arbitrary blunt body. The analysis is applicable to windtunnel or flight conditions, and the heat loadings are either arbitrarily assigned or they are calculated concurrently with the heat-shield response. Surface heating (or cooling) mechanisms accounted for are those due to convection, radiation, homogeneous combustion, heterogeneous combustion, surface material removal by means other than combustion (includes erosion) , and sublimation. Physical and thermodynamic properties of the ablating material are arbitrarily assigned so that calculations can be made for various materials. A typical application of the analysis is given as an illustration. The analysis is machine programmed for numerical solutions usinga finite difference scheme, and a family of computing programs is used. These programs are described and instructions are provided for using them. The programs can be obtained from COSMIC, University of Georgia, Athens, Georgia, 30601.

Book Description
An analytical model is presented for predicting the transient one-dimensional thermal performance of a charring-ablator heat-protection system when exposed to a hyperthermal environment. The heat-protection system is considered to consist of a ablation material and backup structure. The ablating material is further considered to consist of three distinct regions or zones: char, reacting, and virgin material. A FORTRAN IV digital computer program (STAB II) utilizing an implicit finite difference formulation has been written for the IBM 709/40 computer system. The program considers one ablating material and a maximum of 12 back- up materials with conduction or radiation and/or convection allowed between materials. Thermal properties of all materials are temperature dependent, with the properties of the charring material also being state dependent. The governing differential equations and their implicit finite difference formulation are presented. The program input and output are described in detail. The FORTRAN program statements and nomenclature are presented. Also, the theoretical and experimental results are compared.
