Pioneer Rocketplane

Pioneer Rocketplane is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pioneer Rocketplane rather than just read about it. In short: Pioneer Rocketplane was an aerospace design and development company intent on developing affordable crewed space flight. The company is most famous for advocating a horizontal takeoff, turbo-jet and rocket propelled, aerial-refueled, rocket plane concept called the Pathfinder.

Key takeaways

Pioneer Rocketplane belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pioneer Rocketplane to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pioneer Rocketplane from memory before moving on to harder problems.

Reference excerpt

Pioneer Rocketplane was an aerospace design and development company intent on developing affordable crewed space flight. The company is most famous for advocating a horizontal takeoff, turbo-jet and rocket propelled, aerial-refueled, rocket plane concept called the Pathfinder. The company still exists, but is no longer in operation. Pioneer's intellectual property is now owned by Rocketplane Limited, Inc., however Rocketplane Limited does not employ any of the principals of Pioneer Rocketplane.

History

The "Black Horse" study The "Black Horse" study began with a bar napkin at the White Sands Missile Range Officers’ Club on May 12, 1993. The original concept was developed by then Air Force Captain Mitchell Burnside Clapp, who envisioned an aerial refueled, rocket-powered single-stage to orbit (SSTO) vehicle using jet fuel and hydrogen peroxide. This concept seemed a natural match for the Air Force's TransAtmospheric Vehicle (TAV) mission and studies began at the USAF Phillips Laboratory. Aerospace engineering legend Burt Rutan and noted aircraft designer Dan Raymer contributed input to the development of the design.

The private sector Mitchell Burnside Clapp left the Air Force in 1996. Teaming up with Robert Zubrin and promoter Charles Lauer, he founded Pioneer Rocketplane. To help the new company get started, it allied with Dr. Zubrin's research company, Pioneer Astronautics, in Lakewood, Colorado. General Tony McPeak, now retired from the Air Force, joined the company as chairman of the board. During this time Pioneer Rocketplane refined the concept for the Pathfinder rocketplane. It had to require no new engine developments, which would postpone the first flight by years. It had to be built by subcontractors to avoid the time and expense of building an in-house manufacturing capability. Most importantly, it must be able to support the requirements for the new low Earth orbit communications satellites. This led to the switch from hydrogen peroxide to liquid oxygen as the preferred oxidizer, and drove an increase in overall size. Version 2.0 of the Pathfinder concept was delivered in 1997 by Conceptual Research Corporation.

Rocketplane Limited In 2001, Rocketplane Limited, Inc. was formed. Pioneer Rocketplane is a part owner of Rocketplane Limited, but ceased operations as an independent company. Rocketplane Limited purchased the intellectual property of Pioneer and put in place an all new management and engineering team to push the development of the Rocketplane XP. In 2006, it acquired Kistler Aerospace.

Worked examples

Example 1 — a first encounter with Pioneer Rocketplane

Start with the simplest possible case. Write down what Pioneer Rocketplane claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Pioneer Rocketplane 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 Pioneer Rocketplane 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 Pioneer Rocketplane

In research: Pioneer Rocketplane appears in science 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 Pioneer Rocketplane 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: Pioneer Rocketplane is common in secondary-school and first-year university syllabi. It links to neighbouring topics Private spaceflight companies, Space access, Space tourism, so understanding it makes those chapters shorter.
In everyday life: Look for Pioneer Rocketplane 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.
