The TU engine is distantly related to the older X-Type engine — sharing a similar overhead camshaft architecture, but the key differences are the belt driven camshaft (the X is chain driven), and that the TU is mounted in a conventional upright position with a separate, end-on mounted transmission and unequal length drive shafts.

In general, a k-form is an object that may be integrated over a k-dimensional manifold, and is homogeneous of degree k in the coordinate differentials ,, …. On an n-dimensional manifold, the top-dimensional form (n-form) is called a volume form. The differential forms form an alternating algebra.

Tu is a younger brother of Charles Tu, who is a professor of electrical and computer engineering (ECE) at the University of California, San Diego. [5] [6] He also has another brother, Tu Xiang; all siblings became academics. [7] During his childhood, Tu was largely raised by his grandfather.
A non-afterburning variant known as NK-32 Tier 2 for Tu-160 and NK-65 will be used in the upcoming Russian bomber, PAK DA. [ 1 ] NK-65 and a geared high-bypass turbofan variant PD-30 , with a thrust of 30,000 kilograms-force (290 kN; 66,000 lbf) has been proposed for use on new Russian wide-body airliners, as well as the upgraded Antonov An-124 ...
In mathematics, differential topology is the field dealing with the topological properties and smooth properties [a] of smooth manifolds.In this sense differential topology is distinct from the closely related field of differential geometry, which concerns the geometric properties of smooth manifolds, including notions of size, distance, and rigid shape.
In mathematics, a tubular neighborhood of a submanifold of a smooth manifold is an open set around it resembling the normal bundle. The idea behind a tubular neighborhood can be explained in a simple example. Consider a smooth curve in the plane without self-intersections. On each point on the curve draw a line perpendicular to the curve ...
