Интересно, какие перегрузки будут у КК типа Дрим Чейзера при входе в атмосферу при возврате от Луны/Марса?

Варан, нафига такой гигантский аватар?
А что, кто-то собирается возвращаться с Луны/Марса на КК типа Дрим Чейзера?
Или это чисто теоретический вопрос?

Ну а если бы и собирался? Благодаря развитому аэродинамическому управлению велика ли разница - первая или вторая космическая?

Если заранее корабль на это не рассчитывать - может не хватить ресурса теплозащиты. А если рассчитывать - скорее всего получится тяжелее.

Ну то есть два варианта, как и у капсул. Не вижу проблемы и здесь.

Площадь шита больше, тормозить эффективней он начнет в более высоких слоях атмосферы.. Почему должны быть сильнее перегрузки? А в нижних слоях более пологая траектория растянет время торможения и опять же снизит перегрузки.

Да великих проблем нет, просто непонятно, зачем тащить куда-то крылья и хвосты, если можно обойтись капсулой...

Чтобы приземлится тихо и скромно по человечески - в аэропорту,а не бог знает где с поиском десятками поисковиков и спасателей.

Резонно конечно, но надо считать во что встанут эти лишние несколько тонн...

Для корабля, летающего на Луну/Марс, посадочное шасси явно лишнее. Да и несущий аэродинамический корпус не оптимален (слишком много весит по сравнению с конусом).

В лишние несколько десятков тонн керосина и кислорода на РН. Главный-то груз - люди со своими креслами, скафандрами и СЖО. А это всё вместе взятое - всё же очень малая часть общей массы КК. Добавить несколько тонн (да имхо всего-то полторы-две!), пусть даже в виде сбрасываемого экрана, почему нет?

Обеспечить крылатый КК дополнительным экраном для спуска со второй космической всё равно проще и дешевле, чем делать для возвращения с Луны/Марса совершенно другой КК.

Ну, во-первых, совершенно другой КК и так будет, а во-вторых те килограммы, что будут съедены чейзеровскими шасси и крыльями, в длительной экспедиции к Марсу гораздо лучше употребить по  другому назначению.

"Несколько тонн" не будет. У первых КК теплозащита весила очень много (у Востока около 80 кг/м2), но сейчас теплозащита весит почти на порядок меньше. ЕМНИП, у Федерации этот показатель около 10 кг/м2.

Навскидку, площадь крыла у дрим чейзера около 30-35 м2, соответственно теплозащита весит 300-350 кг. Кстати, масса парашютной системы для КК подобной массы была бы примерно 300 кг.
Думаю, именно поэтому Маск хочет отказаться от парашютов при посадке на Марс.

А Маск думает из-за невозможности применения, как и все, кто делал лэндеры на Марс до него.

Sierra Nevada Corporation and the United Nations Announce First-Ever Dedicated United Nations-Dream Chaser® Space Mission

Launching a Dedicated Dream Chaser Microgravity Mission for Member States in 2021

SPARKS, Nev. (September 27, 2016) – Sierra Nevada Corporation (SNC)  and the United Nations Office of Outer Space Affairs (UNOOSA) and have announced details of the first-ever United Nations space mission at the International Astronautical Congress  today in Guadalajara, Mexico. The dedicated Dream Chaser® Mission is targeted at providing developing countries the opportunity to develop and fly microgravity payloads for an extended duration in orbit; however, all United Nations Member States will be able to propose payloads for the mission.Innovating for Positive Impact
"At SNC our goal is to pay it forward," said Eren Ozmen, SNC's owner and president. "That means leveraging the creation and success of our Dream Chaser spacecraft to benefit future generations of innovators like us all around the world."This announcement builds on the Memorandum of Understanding (MOU) signed in June 2016 between UNOOSA and SNC to collaborate on this historic United Nations space mission. The first-ever United Nations space mission is intended to launch in 2021 and will allow United Nations Member States to participate in a 14-day flight to low-Earth orbit (LEO) on SNC's Dream Chaser spacecraft."One of UNOOSA's core responsibilities is to promote international cooperation in the peaceful use of outer space," said Simonetta Di Pippo, director of UNOOSA. "I am proud to say that one of the ways UNOOSA will achieve this, in cooperation with our partner SNC, is by dedicating an entire microgravity mission to United Nations Member States, many of which do not have the infrastructure or financial backing to have a standalone space program."Making Space Affordable
According to Ms. Di Pippo, funding of the mission will come from multiple sources.  "We will continue to work closely with SNC to define the parameters of this mission which, in turn, will provide United Nations Member States with the ability to access space in a cost-effective and collaborative manner within a few short years. The possibilities are endless."Countries sel ected to provide mission payloads will be asked to pay a pro-rated portion of the mission cost, based on the resources required to host the payload and their ability to pay.  In addition, major sponsors are being sought to finance a large portion of the mission costs.Path to Mission Launch
Over the next year, mission partners will conduct briefings to United Nations Member States and potential payload providers about the goals and framework of the mission and to solicit proposals for payloads.  To make the program more accessible to nations without a highly developed space industry, UNOOSA will offer technical support to countries that lack expertise or experience in developing microgravity payloads. Payloads will be selected in early 2018 to allow time for development and integration into the Dream Chaser spacecraft for launch expected in 2021. SNC's Dream Chaser is the only reusable, lifting-body, multi-mission-spacecraft capable of landing at commercial airports or spaceports able to accommodate large commercial aircraft – anywhere in the world. This offers the opportunity to land the United Nations mission in any licensed Member State supplying a payload on the mission. SNC is currently working with airports and spaceports to be granted a Federal Aviation Administration reentry license for  commercial Dream Chaser missions. Recently selected to provide cargo delivery, return and disposal services for the International Space Station (ISS) under NASA's Commercial Resupply Services 2 (CRS-2) contract, Dream Chaser is a safe, affordable, flexible and reliable system capable of crewed and uncrewed transportation services to LEO destinations such as the ISS.

THE DREAM CHASER® FOR EUROPEAN UTILIZATION PROGRAM TAKES FLIGHT WITH MEMORANDUM OF UNDERSTANDING
 
SPARKS, Nev. (October 11, 2016) - The Dream Chaser® for European Utilization (DC4EU) program kicked off its pilot phase with the signing of a Memorandum of Understanding (MOU). Sierra Nevada Corporation (SNC), Telespazio, the European Space Agency (ESA) and OHB System AG (OHB) will now assess the feasibility and commercial viability of the DC4EU dedicated mission to provide affordable, independent European access to low-Earth orbit (LEO) via the Dream Chaser space utility vehicle (SUV).

"The Dream Chaser SUV is the only reusable, lifting-body spacecraft with a commercial runway landing capability anywhere in the world – offering safe, affordable, flexible and reliable transportation to space," said Mark Sirangelo, corporate vice president of SNC's space systems business area. "That is exactly what our industry team is offering Europe during the ISS transition phase."
 
The DC4EU Pilot Phase
The DC4EU mission was one of eight sel ected by ESA to begin pilot phase implementation in 2016. It offers the best value for European access to LEO by providing a full end-to-end mission capability using the unique attributes of the SUV including, compatibility with the European Ariane 6 launch vehicle and the ability to land on suitable runways for near-immediate payload access. The objective of the pilot phase is to demonstrate the technical and programmatic feasibility of DC4EU, which includes the preparation of a business plan highlighting the partnership viability for both private and public interests.

"Commercial partnerships are a new element of the ESA Space Exploration Program. They open up space exploration for private sector-led initiatives and offer exciting opportunities for advancing the implementation of the ESA strategic goals for space exploration in novel ways and for enlarging the stakeholder community actively engaged in exploring space," said David Parker, ESA director for Human Spaceflight and Robotic Exploration.
Dr. Fritz Merkle, Chief Marketing Officer and Executive Board Member of OHB Group highlighted another key use for future missions, "One national and international mission goal is a sustained utilization of human-tended infrastructures beyond the life of the International Space Station (ISS) with increased cost efficiency and responsiveness to utilization interests."

Giuseppe Aridon, Vice President Strategy and Marketing of Telespazio explains: "DC4EU could represent a valuable platform to enable independent European access to LEO through a 'customized' European variant of the Dream Chaser spacecraft. We are willing to explore the potential of such a promising solution, that could be a major element for the setting up of the future European LEO service missions ecosystem, that will see the Dream Chaser operating alongside other European assets and infrastructures for first of a kind transatlantic partnership in this field, with true a global perspective!"
 
DC4EU Team
In March 2015, ESA released a Call for Ideas (CFI) for ‎strategic partnerships with the private sector in the field of Space Exploration. In response, OHB System AG (Germany), Sierra Nevada Corporation ‎‎(USA) and Telespazio SpA (Italy) teamed to create what is now called  Dream Chaser for European ‎Utilization (DC4EU). ESA has sel ected the DC4EU mission out of 60 partnership ideas for a pilot phase implementation. Developed by SNC, the Dream Chaser SUV is contracted by NASA to provide cargo services to and from the ISS under the Commercial Resupply Services 2 (CRS2) contract. The uncrewed Dream Chaser spacecraft variant is capable of transporting pressurized and unpressurized cargo to and from LEO with controlled entry and landing on approved airports.
