Reference excerpt

The Temco XKDT Teal was an American rocket-propelled, high-performance target drone, built by Temco Aircraft for evaluation by the United States Navy in the late 1950s. Production was not proceeded with following evaluation of the type.

Design and development The XKDT was designed for use an inexpensive and expendable air-launched, high-performance target drone. Its design utilized a low-set swept wing, and an inverted cruciform tail; the structure of the aircraft included aluminum honeycomb wing construction and extensive use of magnesium and fiberglass in the fuselage. It was intended to reach speeds of up to Mach 0.95. The Teal could be launched at any altitude of up to 50,000 feet (15,000 m); speed at launch was between 163 knots (302 km/h; 188 mph) and 248 knots (459 km/h; 285 mph). Following launch a dual-thrust solid fuel rocket motor ignited; thrust was 150 lbf (670 N) for the first four seconds of powered flight, followed by 50 lbf (220 N) for approximately 500 seconds propulsive time. Control was provided by a three-axis autopilot; radar reflectors and infrared flares provided an assist in tracking the drone, and at the end of nine minutes' flight time a self-destruct device would be activated.

Operational history The first flight of a XKDT-1 took place in September 1957; most flights utilized a McDonnell F3H Demon carrier aircraft. Following the conclusion of the evaluation program, no production contract was placed; supersonic targets having become preferred.

Worked examples

Example 1 — a first encounter with Temco XKDT Teal

Start with the simplest possible case. Write down what Temco XKDT Teal claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Temco XKDT Teal before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Temco XKDT Teal ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Temco XKDT Teal

In research: Temco XKDT Teal appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Temco XKDT Teal in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Temco XKDT Teal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s United States special-purpose aircraft, Aircraft first flown in 1957, Cancelled military aircraft projects of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Temco XKDT Teal outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
