Разгон на земле.
Здесь появляется трение f.
f = 4 в TDM и 6 в TF.
Результаты.
Правильный старт. Стартуем прямо, не поворачивая (cos(gamma) = 1). За один фрейм до достижения скорости v_max (достигнув скорость v1 = v_max * (1-a*T)/(1-f*T)), начинаем поворачивать: cos(gamma_best) = [(1 - a * T)/ (1 - f * T)] * V_max / v.
Достигаем скорость v_ultimate = v_max * sqrt((a / f) * [(2 - a * T) / (2 - f * T)])
cos(gamma) при этом уменьшается до [(1 - a * T)/ (1 - f * T)] * sqrt((a / f) * [(2 - a * T) / (2 - f * T)]) = = 0.592, gamma = 53.7 градусов в TDM.
Максимальная скорость, при которой ещё имеет смысл разгоняться по земле
v_reasonable = sqrt((V_max*V_max*aT*(2-aT) - 30^2)/(fT(2-fT)))
Ultimate and reasonable ground speed:
